ok i got the tranny coming what about the aluminum motor mount and spur gear will the old ones work or are they different

No, you need a new motor plate and a new style slipper clutch with new spur gear.

Anyone have a link to detailed info on what needs to be modified to put 3.3 shafts on a 3906 (with stock 3906 diff's). My B'in law just sent me an email and said that the shafts I told him to get dont fit...I forgot that the diff's are different!
