Should I go with the a833 conversion?

if you have a 904 in it right now, the tranny mount should fit on the 833.
I converted 3 cars now. 2 abodys and one b body. All three didn´t need a different tranny mount
If you want to save the money on a Z-bar and all the linkage, you should consider a conversion to hydraulic clutch. Its really cheap and its a nice feeling in the clutch pedal!
I have a post here somewhere from my hydr. conversion in my old Dart.
