833 OD Ato E body

I went the other way and put a long tail shaft (B/E body length) A833OD in my 68 Barracuda.

It was a simple and straight forward swap. There are only two significant things to do. Make a bracket to bolt to the rear mount that positions the shifter forward to the A-body position. And, shorten the drive shaft.

To go the other way would require the bracket to move the shifter back and the drive shaft would need to be lengthened.

Bigblockdart.com has a good write up on putting the long tail shaft into an a-body and even have a dimensioned drawing for the bracket.
