A body with an A833 and a Gear Vendor installed

That’s the kit I was referring to. I called Passon and Jamie said he still sells the gears by themselves. He said at that time he only had 3 sets left and would not get more until late August.

I would strongly advise against the OD gesrset. I had the set in my Dart and the shifting was horrible. I couldn't downshift into 2nd without darn near coming to a stop. The entire trans was rebuilt with new syncros/hubs. I tried getting support from Jamie, no dice. Called Brewers and he knew exactly. Said he could repair it for $400. I was over it. Plus the OD ratio is .80 that isn't that great.

Try searching 18 spline OD gesrset and see how many are actually using it, not many. GV/TKX on the other hand, all over the place in multiple applications.
