Ok, so since the body is now going to come off, there are other things I might want to consider.....like switching from the C4 trans to an AOD, 4R70W, or maybe even a T-5. I've found some info on modifying the x-member to fit the AOD but I don't know about the 4R70W or the T-5. Of course if I go with a T-5 I'll have to come up with a clutch pedal plus a few other things. You guys have any thoughts on these options for the 35-40 frame?
