Is there anyone who know the original slip yoke for the AAR cuda ,was it 7260 , 7290 or is both type correkt?

The parts book doesn't make any distinction for the AAR, it uses the same 7290 as a 340-4.

Thanks,

I do not have the numbers memorized, but AAR & T/A driveshafts use the small u-joint in the front & the large one in the rear.

What is the code for it on your broadcast sheet if you have it?

Barry,
Do these drive shaft numbers look correct?
I guessed at the first 4 numbers.

AAR - 2883769
T/A - 2883782

Yep, correct on both.

My 70-71 parts book shows both numbers, but the only u-joint referrenced for them is the 7260.

This is odd.

My 1970 318 barracuda had the big & little driveshaft also, but there is not a referrence in the parts book that spells out two different u-joints that I can find?

Mistake in the book?

Is it shown in a different revision?

Or am I just missing a connection somewhere?

I have seen the big & little combinaion in every A53 E-body I have checked.

Barry,
Checkout the length difference between the drive shafts.

The ones for the T/A and AAR are .250" longer than their counterparts.

AAR - 43.85" - 7290
Cuda - 43.60" - 7290

T/A - 45.85" - 7290
R/T - 45.60" - 7290

The 7260 u-joint on one end could explain the additional length.
