Help on wheel fitment 65 Canso V8
Permalink  

New to this site,but have been lurching here off and on for over a year .
I do not have a Canadian Poncho--yet!
But I do have friends that do.
One in particular is a customer of mine at my shop.
He wanted to dress up his 65 Canso 2 door hardtop factory V8 car with some mag wheels.It has the 5 on 4-3/4 bolt pattern and modern disc brake conversion up front,drums in the rear.
I have fitted many vehicles in the past at my shop over the years but never had the pleasure fitting an Acadian.
He has owned  the car for over thirty years,and was last driven twenty years ago.
He has been working on the car to get it ready for next summer.
He came in and asked for 4 inch backspacing and a 15" inch rim.
Since the car was at his home and not driveable I went by his information over the counter.
Typically I prefer to see the car.
He picked up the wheels and was very happy until he put them on,dropped the car and they rub against the fenders in front and the car sits on the outside of the rear tires.You cannot put ypur fingers between the wheel lip and tire.
The tire size we chose is 2156015 which has a diameter the same as  the 6.95-14's that came off the steel  14X6 rims which have backspacing of 4 inches.

I went to his home and seen it for myself.
The wheels stick out too far.
I have a few questions to any 62-67 Acadian owners who have aftermarket wheels on their cars.
1.What is the best backspacing and offset to use on this car??

2.Anybody had difficulty finding aftermarket rims to fit without going the "custom order" route (translate to expensive cut to fit rims)

3.Does the aftermarket disc brake conversion (brand I do not know) widen the front track? Does it affect the front wheel offset?

4.He wants an aftermarket wheel not a GM wheel.

5.As a reference,what is the backspacing on the factory later GM 15" wheels that DO FIT the 62-67 cars?

I feel bad for the guy.
Plus I have to answer to my boss about a set of wheels/tires we are stuck with and cannot return.( I can sell them nooo problem).
I never had a fitment issue until this car came along.
I know these cars are different -but never knew how much more unique they really are.
I will get pics tomorrow.
Any help/advise is appreciated
Thanks in advance,Leaburn

Welcome to the site!!!   

I used to sell many rims and tires combos, as you are doing..
I will wait until someone else chimes in..  

I fitted lot of 67 up Novas, but my only customer with a 1965, had a straight axle grafted on  lol    You could change fron tires, but the smallest 70 series is a 215/70  I do think a disc brake conversion will set it out a little....can you talk him into the same aftermarket rim in a 14 for front?   most stock steel rims (15) are 4.5 back space

I am leaning towards the 4" backspacing is not enough.
The 7" rim goes out towards the fenders.
So,maybe i shopuld search for vendors who offer 4.5" backspacing in a wheel he wants.
The extra half inch INWARD should help.
He may have to get his wheels custom built to fit.

62-67 Acadian/Chevy II/Nova's need more backspacing than standard.
You should measure the car and order the correct backspaced wheels.
Here's some examples: http://www.2quicknovas.com/6267.html

Great info from that site Joel.

La Wrench n, from the info you have given, it looks to me the front wheels will work but with a 195/60 R15 tire. There is no room on the back of a 65 for a 15" wheel with 4" BS. The BS has to be 4.5" with a 15x7 rim on the back.  His tires should fit the rear if he has the correct BS wheel.

Here is a great way to measure and compare wheel and tire combinations.....it's funbiggrin

First off, recently they have come out with "0" offset front disc kits but most anyone that did a conversion prior to last year would see a 1" offset to the outside with disc brakes and the OEM spindle.  We put 4 wheel disc on my Acadian and it set the wheels out 1" front and back.
In terms of the rear wheel inner fenders on the 62-65 Nova/Acadian there is less clearance inside the wheel well about 2" above the lip.  Most people put the mounted wheels and tires on and they look like they have 1" clearance from the lip of the rear wheel well opening.  As soon as they drive away, heat the tires or turn a corner the tire rubs up inside the wheel well.  They hear it but when they stop all they see is the rub mark on the sidewall.
The 66-67 rear wheel well has more clearance in that rear area and can usually run a 1" wider rim without a rub.
We put 17"x7" Coys on my Acadian with 4 3/4" BS.  You need a minimum 4.5" BS with a 7" rim on the stock axle and drum brakes.  We tried to order 5" BS on the 17x7 Coys and they would not make them unless we went to an 8" rim.  That was in 2007 and I have heard since then, they keep the 4 3/4" BS in stock and will make a 5" on request.  My tires are 45mm on the sidewall which I like with the 17" rim.  It is much easier to make this combo work than trying to fit a 60 series tire.

I spoke to my client today and he did use his original spindles for the conversion.That explains the zero clearance up front--along with the 4" backspacing.
In terms of the rear wheel inner fenders on the 62-65 Nova/Acadian there is less clearance inside the wheel well about 2" above the lip.  Most people put the mounted wheels and tires on and they look like they have 1" clearance from the lip of the rear wheel well opening. 
Ditto here.he tried rolling the wheel lip but it did not make any difference.The issue is above that area.

We put 17"x7" Coys on my Acadian with 4 3/4" BS.  You need a minimum 4.5" BS with a 7" rim on the stock axle and drum brakes.    It is much easier to make this combo work than trying to fit a 60 series tire.
I learned that one the hard way,LOL!
Right now he needs to roll the car to paint.I will search for some old ugly O.E. rims that clears his disc brakes just to get it to the body shop.
While it is in the paint booth,it will give me time to find wheels that will fit properly and still suit his taste.

I want to thank everybody for their help. worship.gif

Update....
The owner did inquire about using the Corvette Rally wheel in chrome in a 15X6 with a narrow tire.Problem is the Backspacing is 3.75".
15X7 is only 4" or 4.25" max
OK in front,but I am afraid they will not work in the back.
Custom backspacing in a chrome wheel can be expensive and a very long wait.If it were a painted wheel they probably would be turned over in short order.

I am at my wits end since nobody has a wheel off the shelf to fit this car.
I have exhausted all of my Canadian suppliers and my company does not deal with any American wheel suppliers-broadmarket nor custom.
Custom wheels are inevitable.

But for the time being...
The local junkyards have no wheels to fit just to roll the car to the body shop.
The damn thing is imobilized and its progress has literally stopped in its tracks.
The owner is really anxious to get his Canso finished.(It is an SD,confirmed that as well.Rare car indeed.)
I tried a set of S-10 4X4 wheels and they do not fit in the front.(Perfect for the rear,though with 5.5 backspacing)
What can I use for now that will clear the front disc brakes??
Thanks to forespeed's info we did confirm the disc brake conversion did change the front offset.

 
Despite the situation,I am taking back the new rims and tires and try to do good by my customer.
My boss is already pizzed at me as it is.
Any help is appreciated,thanks in advance

a stock 15 x 7 vette ralley with a 235 /60 / 15 will fit out rear. what about ordering 15 x 5 with 185 SR 15 up front? I can't speak to the fronts with disc brakes, but this combo works on stock drums.

Well,I got things ironed out.
I am returning the 211 wheels,and got my client set up with Stockton for a set of Corvette rallys painted silver and using the plain chrome caps and beauty rings.
Bobby at Stockton are doing 15X7's with 4.5 backspacing and turnover time will be 2-3 weeks.Chrome one would take longer and much more money butt my client settled for the painted ones wheich will look just as good.
.
In a way,I feel partially at fault by not really digging deep on this application.
Plus not seeing the car first hand,and trusting the  info given to me was a handicap.
 
Thanks to everybody who helped me out.
No pics yet,but as soon as the opportunity arises I will try to take some.
