Powerglide conundrum


I am a proud owner of a 1960 Parisienne 4 door vista hardtop.

I'm swapping the original 261 for a period correct 283.  I found  a 283 and transmission in a 1966 Parisienne for a donor.

Then I found that the transmission on the 283 had a "fine" spline while my driveshaft has a "course" spline.  My first thought was to use the PG from the 261.

But it's specific for a 6 cylinder so I can't use it for the swap. 

I located a 3rd PG, but it it needed an adapter plate and there seems to be no way to connect the torque converter to the flex plate (unless I connect the tranny afterwards).

Any suggestions or solutions for me?  Let me know what I'm missing.  Better yet, where does one find a fine spline for the driveshaft?

Thanks,

Bake

Fine spline available from a truck shop, or Napa or Canadian tire maybe. order one for a 1966 Chevy. Maybe check the overall length of the ironglide compares to the 66 glide, face of block to end of tail shaft to make sure they are the same length. The motor mounts that bolt to the frame are taller for the 6 than the 8 as well.

And you could run a wanted ad here as well. I won't be shocked if a member here has a yoke for sale. You just have to make sure it's for the right style of u-joint. You need the yoke for what is called the outside snap ring, meaning the snap ring is visible at the outer end of the U joint cup. The yoke will have a groove in the hole where the cup presses in. The groove will be about 1/16" - 1/8" in from the outer edge of the bore. If the yoke has no grooves in the bore where the cup presses in, it's the wrong yoke.

Thanks for your reply!  I'll check the local NAPA for sure. There is a length difference of about 1.5 inches.  Not sure how I am going to solve that one!  I'm expecting to lengthen the drive shaft once I have all the pieces in place.

Dana/spicer 2-3-6081X is the yoke part number.

Might be better to find a longer front shaft and shorten it- I have no experience with adding to the length so may be wrong there. Find a good local heavy truck shop , they cut and balance shafts all the time. Make sure they clock the driveshaft the same as it is now when they put the 2 pieces back together. If you need a new center bearing, look closely at the welds on the base, Ive had quality problems there.

 I`d work with the `66 Aluminum PG.

Well, folks, I've solved the spline/yoke challenge with the Spicer yoke found at the NAPA dealer. Thanks.
See my next question in a new feed . .
