trans/transfer interchange??

907 Views 6 Replies 4 Participants Last post by  gottagofast
I have a 1977 Chevy 3/4 ton 4x4 350engine NP435 trans, 205 case. My trans and transfer are going south on me and I'm contemplating my options. I have a spare 208 case, but I'd lose the durability of the 205 and have to change driveshafts, and still need transm. repairs... My real question is that I have access to a 79 Ford bronco parts truck, 351M-435 trans, 205 trans- will the FORD and Chevy trans/transfers interchange if I use my bellhousing? The mounts look the same, but I can't find any info to tell me yes or no.

I do know it is a 435, synchros and bearings are pretty well shot, this was originally an oil well service truck for years, then was run as a mud bogger, then I got it and use it as my work/camping vehicle (regularly hauls 2+ tons of materials) generally overused and abused and I was just trying to find a cheap swap out option, rather than take the time to tear down, order parts and rebuild, also, I think the transfer shift shafts are worn out as it won't hardly stay in Low range. I can use the 208 because I have compred the adapters and they interchange, and I'm pretty sure the input splines are the same - the 208 is just about 6" inches longer on the rear output side, wich meand I need to shorten/replace my rear shaft.
Thanks for the inputs though- more food for thought.
