I need help with a steering gearbox rebuild

[superdav]

I need a rebuild kit for my steering gearbox and I've learned Amazon's car part finder is not trustworthy
so far I've bought
Edelmann 8522 which Amazon said was the right one for my 84 2wd and it wasn't, the first part I tried to put on was the wrong size, a piston seal

Edelmann 7857 on Rock Auto and that kit is not right either. The bearings are way off.
