That was going to be my next question! I have a broken 4L60E on my garage floor right now and the only difference I can spot in dimensions is the output shaft.

So I can pickup a shaft for a 700R4, put that in and will directly bolt in place of a TH350, or it still slightly longer? Either way, the engine will be going forward. Sure would be nice to actually be able get to the distributor.
