Glad to help guys!
So Moparnut, Since you already have a 23 spline 833, 4sp car, all you need to put one of these in:
1. The trans. (833 OD with B-E body type tailshaft) (from a truck) I paid $75 for one at a swap meet.
2. Take the front bearing retainer off (4bolts) and have a machine shop turn down the outside edge to 4.80" (about$20), to fit the bellhousing hole.
3. Pull the old 833,move the shifter mount over, then install the 833-OD in. Mount shifter and linkage.
4.Flip the 3/4 lever like in the pics and slightly bend the 3/4 linkage where it might hit the trans cross-member.
5. Drive.
