Thoughts on gear vendors OD

[TexasRoadRunner68]

Looking into possibly going with a gear vendors for my 70 charger 4 speed. I don’t want to cut the car up to put a modern trans in it. Does anyone here have one on the back of their 4 speed? I’m building the car to drive, and would like to do power tour with it.

What do you have in the back ? A set of 3.23's would not be a bad choice to do a tour trip.

3.54s. With the gear vendors 4.10s might be doable.

"Cut the car up"?
Nobody cuts their car up to install the popular Tremec 5 speed. There are several threads on the forum about installing these, I had one 4 years ago but THIS one covers the updated Tremec TKX version of the transmission that is slightly more compact:
Tremec TKX 5-Speed Conversion

See post # 286.

The cuts are in the tunnel exclusively.

This requires a much slimmer cover to close off the opening. Cardboard was used to make a template:

Steel sheet metal was then shaped to fit.

Seam sealer and it is weathertight.

The cutting was minor and could be reversed if someone wanted to return it to stock. The original carpeting even fit!
My resistance to the Gear Vendors was the not-so-great .78 overdrive ratio and the super duper long, cantilevered add-on design of the GV unit makes for a shorter driveshaft. This is a bigger problem in a shorter wheelbase car than a B body. I'd be more inclined to use a GV with a 727 since Big Blocks don't have many choices for overdrives in automatic transmissions.

I guess I was mainly referring to the tremec 6060/magnum swap.

You can buy a LOT of gas for the cost of a Gear Vendors install. Put 3.23's in, and be happy.

Cast iron A833 OD is an option.
