RE: A833 OD questions

[ledman_70@xxxxxxxxxxx]

Main and cluster gearsets are different, the rear trans mount location 
is different, and the bearing retainer is 5.1", whereas the eary 833's 
are 4.3", and the later ones are 4.8". There are several differences, 
but I have been given enough info to realize it's doable, just gonna be 
a little work...but hey, what ISN'T a little work in this hobby, 
right?!?!
