Thinking about a Gear Vendors OD. Can Anybody Give Some Guidance?

I have run the passon 18 spline hemi overdrive gears in my a833 for a bunch of years. No complaints
28" tire and 4.30 gears. Cruises awesome.

I just finished my install of a t56 into the same car but now with a big block. I have not run the car much due to other issues. I swapped in a dana 60 with 4.10 gears now.

The passon od is now going into a different vehicle.

I have another passon od gearset for another future project. Just have found the project yet :-D
