Any one put a gear vendor unit in 70 Duster. If so any modifications needed to make it fit. And does anyone have one for sale. Thanks
I have one in my 67 Dart 340/904. I don't use the controller box; a simple push button on my shifter controls the OD solenoid. When I run 1/8 mile 2 gear OD is perfect with 4.10 gear and 28 tire.

With mine, I bolted the unit up to the A833, then put a jack under the Gv, and rammed the sucker into the tunnel 'til the suspension unloaded. Then I reshaped the tunnel from the cab side, with a bfg until it fit. Then I slotted the late-style mount about 1/4 inch, or whatever I could get, and called it done. It has never tapped the floor, probably because I have the engine chained down with a Schumacher restrainer.They said it was good for 1200 horsepower, so I figured it could take a few hammer blows. It doesn't leak up there so I guess they were right.
I had to cut my H out too, from the TTI system. I really missed the torque, and spent all summer looking for it. By next summer I had a 3.09 low in there, and that was the end of the softness. Now those 3.55s take off like they were 4.12s.And with all the torque I found last year in the fine-tuning, she's a rocket now.
I wanted to keep the 3.55s cuz that makes her a 4-gear car to 93 in the 1/8; 2 splits and 1 pull. Also it makes 65=2240 just above were my 230 cam vacuum peaks, so I thought that would give me the best shot at fuel-economy. I was wrong, that 230 has no economy in her, not with any other gear or any other carb. It's just baaaaad no matter what,lol
Flipping the toggle, I take to mean "hot-wired" no computer control right?I have one behind the Hemi / Passon aluminum case A833 in the silver Duster....To keep the engine angle close to factory, I cut a 12" section out of the pinched part of the tunnel aft of the 4-speed hump and replaced it with a section of tunnel from Chris Alston. Shorten driveshaft a given
I made several attempts to use it in a drag scenario and found it wasn't consistent with too much lag between flipping the toggle and the shift. Great for super slab cruising over 65 MPH though.
I have one in a 68 Barracuda 360/A833.
The only mods were to pound a lil dimple in the tunnel to clear the largest diameter at the castings parting line. I used the late-style rear mount, and I mighta slotted the mounting holes a little deeper in the late-style rear mount, to drop the trans a hair. Yeah I sorta remember doing that, but it wasn't much.
One thing I didn't like, was that GV would not sell me a separate adapter for my winter-engine with a 904. If I wanted one, I would have to return my A833 adapter, pay the difference, and 6 months later send them the 904 one back to get an A833 one, at additional cost,again.
I get that it's their business but that turned me right off. Had I known that before putting my money down,I think I mighta passed.
Another thing that irked me was that they would not sell me the tools to rebuild that sucker, and they charged 50% of current retail to rebuild it when I puked it.
Yeah I guess I'm still sore about that.
If I was to do it again, I'd just turbo my beast and run hiway gears, and not call GV. Almost same money and com'on who doesn't want a turbo'ed SBM?
I guess I could sell you mine, but you'd have to buy the heavily modded A833, and the clutch, and the backset shifter, and the pedals and everything I got that makes it work so well, or just the whole car,lol. At 65,I'm getting ready to buy a wheelchair,lol. Not for me mind you.
PM me, I made roomAre you serious about selling your setup?
