A-body 4 Speed Shifter Setup for A833

In that case, why does it have to be an A-body shifter? Why not just get a factory B or E body complete setup?
B body is too close, E body is too far. I already have an A230 with the setup and the truck is running/driving condition. I don't want to have to reconfigure everything again. An A833 from an B/E body is a direct bolt in. The A230 I got at the time of building was free so I rolled with it. Knowing what I know now, I would've just got an A body tranny, but I can't do it now without redoing the driveshaft, etc.
