A body with an A833 and a Gear Vendor installed

This seems like a real hodge-podge of an arrangement.
I have also been of the habit of trying to make something work that wasn't done before all in the interest of saving money.
Sometimes it works out, other times it is a complete mess that I've tried to make work.
Why not just default to a Tremec? The OD ratio of the Gear Vendors isn't great. The Tremec is a .68, an older TKO can be had with a .64.
Either way, you're looking at some floor pan modifications.
Is this a money issue? Maybe you're just one that likes to do it different?
It is great when one can find a lower cost way of doing something but a GV on a 4 speed manual seems convoluted and more complicated than an overdrive transmission swap. Imagine with the B trans and GV how short your drive line will be too.
