A body a833 into 70 Challenger?

[DONALD J KONRAD]

I'm looking to buy a 70 Challenger. It's 318 with 904. I would like to convert to a 4 speed. I have a 833 out of an A body. Can I change the tail housing or is there an adapter? Or trade for E body trans? I would like to know before I go forward.
Thanks

Used A-body four speeds are rarer than b/e body four speeds. I would sell it and get the right one. You might even come out ahead. If you have the tail shaft and output shaft, you can swap them out and then sell the shorter tail shaft and output shaft.

You will need to upgrade the driveshaft as well.

Good advice here, sell the A body trans and buy the more available B/E.

That said, if you are willing to spend the money, anything is possible. Check with Brewers and/or Passion for parts.

I agree you could modify the A body 833 but why ?
you even have the option of installing the 833 OD version from a van or truck if you want to .

IMO, I wouldn't worry too much about a trans swap till I had the car.
Converting is pretty involved if you've not done it previously. You'll make it more difficult trying to use that A body trans.
In the interim, figure out exactly "which" A body trans and it's condition you have so you can market it. Some are better/quicker sellers than others.

Good point on the a-body four speeds. The 68 and later have a 30 spline output shaft for the driveshaft and is more desirable than the 23 spline earlier four speeds. Brewers is a good source for info on mopar four speeds as stated before.

PS. I converted my 71 Barracuda from a 904 to a four speed, so feel free to PM me if you have any questions. Rod

I think I seen on FABO in other stuff for sale or wanted or the for trade there is a guy with a b or e body 4 gear wanting an A body 4 gear. Kim

You can always add a Gear Vendors and use it in the Ebody.

not really as the shifter location is in the wrong place , better to seel it & find a B/E/ Truck/ Van 833 & install that

So are the truck van overdrive 833 the same size externally as the b/e body 4 speeds. I have a van with the od and plan on putting it behind a 300 hp 360.

Where are you located? I might be interested

I'm thinking the lengths are but you might run up against the shift adapter bosses not drilled and tapped........
