you will need three distinct cases to cover Mopar applications, A/F, B, and E.



Why?

Chrysler had one case for all three, only the tail shaft and associated parts varied.



Excuse me, three tail shafts.

Anything made for these cars shouldn't be weaker than a 23 spline A833.




Valid point. So, since all new transmissions are rated by lb ft capacity, where would the venerable A833 fall in this range? It certainly is a strong trans, but by no means is bulletproof. While a slick shifted crash box may have lasted for a dozen passes at the dragstrip behind a high output Hemi in the hands of Mr. Sox, I can recall a few DNFs from the 1970 Trans Am season for gearbox problems with engines that had much lower specific output than the Factory Experimental, Modified Production, and fledgling Pro Stock class.
