    Yes, after you switch out the rear output shaft to a 4x4 shaft.

    Funny that you mention this...

    I recently saw an article in one of the mags about an Atlas that bolts directly up to a 2wd T400. Sure, you gotta rob a bank for the purchase of the Atlas case and adapter, but at least the tranny would be cheap....! /forums/images/icons/smile.gif

    Short tailshaft 2wd 400 tranny's will hook up the short female input shaft on a 205 t-case easily. Both have the shaft stickout of around 4 1/2".

    I think the bellhousing is different, so bolting the inspection cover could get tricky!

    The TH400 will work if you have the short shaft tranny and short female input shaft on your 205...I know because I am running one in my truck right now. And for the record, the bellhousings are the same, 2wd vs. 4wd, SBC vs. BBC. It's the Pontiacs, Buicks, Olds, etc. Bellhousings that are different than Chevy's. For good info on this contact www.4xHeaven.com

    No, bellhousing are all the same when fitting a BBC or SBC.

    The bellhousing are different when using the 6 bolt dust cover compared to the thinner steel or plastic 4 bolt dust cover.

    Other than that, they are the same unless you get into messing with BOP stuff, then you need a BOP tranny. /forums/images/icons/wink.gif

    I am also running the short shaft TH400 with my converted 205 short input. Runs great and I even was able to use the inspection cover from my TH350. Gotta love the swapability!
