Who can tell me if i can swap out the bellhousing section off of my 318 727 with a regular BB 727 i got layin around, and mate it to the tailshaft section and transfer case......they are both 727's, right? Is this the way everybody does it or do i need to locate a "so called" BB 727 4x4 trans? Please help!

You can't swap out bell housings on a 727. It's a one piece design and blends with the rest of the transmission body.

You can swap internals between a SB and BB 727 and you can swap tailshafts between 2wds and 4wds.

For the most part, yes. Keep in mind that there are some variances which may not work (Such as overdrive 727s and such)

Aren't the OD versions of the 727TF the A-518 and the A-999?
I apologize. I should have said that there were some variances with some 727s having lock up torque converters, not OD.
