I'm curious too. When I picked up the 68  ex police/RCMP car that 67 Poncho now owns, I mounted 70S era seven inch ralleys on the front and they wouldn't turn/roll. Had to round up some other steel rims to tow the car home. I can't remember what I used now, that was a while back. What's on there now Vince?

I've got the 15" original ralley's in my garage from my 70 2+2's, I've upgraded both cars to 15 x 7's.  The ones from my hardtop still have their Uniroyal twin white stripes on them, but the ones from my convertible have other twin white stripes mounted on them.  I'll see if I can check the codes on them, and I can't remember if they're 15 x 5" or 15 x 6", but I suspect the former.

Weird. I remember how baffled I was that the 7 x 15s hit on the calipers. The car had no diff so I had to drive 45 minutes back home for more wheels. In hindsight I should have gone with a trailer in the first place,  lol.

Here is a shot or two of the 67's rallys.  They are in primer now but  they were originally black which was the body colour of the car.

Ken, are they off the 2+2 that you dragged here for me? (I would think not as she is blue) 

Yeah Vince as far as I know they were off that car.  Funny, I seem to remember that car as black. The wheels certainly were black though, at least when I bought them..

The following is specific to the 67 through 70 Rally Wheels usage on the Canadian Chevrolet & Pontiac B-bodies:

I do not have the list accessible, but on the Canadian B-body Chevrolets & Pontiacs 67 through 70 were the years Rally Wheels were offered as an inclusion with Disc Brakes (67, possibly early 68s) or as a standalone option (68-70).

67 came standard with 15x5 except wagons with would have been 15x6. Cars ordered with 70-series tires also would have come with 15x6. In all cases for 67 Rally Wheels were included with and offered only with J52 Disc Brakes.

68 started out like the 67s until the 15x5 size was depleted, then Disc Brakes came with 15x6 Rally wheels. For 68 Rally Wheels were no longer automatically included with Disc Brakes though 15" wheels were used, and you could also order 14x6 Rally Wheels on drum brake cars (15" as well if you desired 15" tires).

69-70 all Rally Wheels were 15x6 and were a separate option independent of J52. Rally Wheels were standard on the 1970 2+2.

Disc Brakes themselves were of the 4 piston fixed caliper design 67-68, then a single piston floating caliper design starting with the 69s.

I knew you'd come through Cam, that is amazing! its like people say to me when I start talking about Quadraphonic eight tracks, "How (and more importantly) why do you know all this stuff?

Thanks a bunch!
