Personally, if your 4x4 frame is too rusted, I would find another frame. They are a dime a dozen from 73-87', and relatively cheap. Also, your th400 will not bolt up to the transfer case. You would need a th400 out of a 4x4 (I think, K case) and adapter to bolt up to the transfer case. Personally, I would sell some the parts off of your existing 4x4 chassis, and buy another chassis. The frame must be pretty nasty as you are california, and they are typically a lot cleaner than found around here. To me though, it would be much more work and agrivation to make a 2wd chassis work when there is an abundance of 4x4 chassis' around. Trevor
