driveshaft lengths

well actually :

what i was doing is going from 904 to 4 speed in a B-body

in B-bodies the 727 is same length as a 4 speed and the 904 is shorter ....

the car has a 904 now so i need to shorten the driveshaft to 727/4speed length.

if it were an A-body the 904 and 4 speed are same length
