Another 4x BB swap thread

[jwhitfield]

I figured that I set this up as a new thread, maybe it will get more response.

There seems to be several of us planning a BB swap. As I've said in the past, my original thought was that the job would be relatively simple. I too thought the 4x4s came with BBs. I've since learned otherwise. There seems to be two trains of thought out there. 1. You don't need to move anything forward, but everything is a tight fit. Some minor grinding and love tapping. 2. Move everything forward 2-2.5 inches.

I have yet to start my project, so I haven't got a good look at the components and crossmembers. My questions are with respect to the relocating of the driveline.
When you say move everything forward I'm assuming that means engine, tranny and transfercase. How is this done exactly? Is there enough space on the various crossmembers and supports to drill another set of holes or do you have to move those as well?
How about moving things 1", is that a good compromise?

Sorry for the length here, but if I take on this project, I'd like to get it done in my life time. The more I know up front, the better prepared I'll be to make the decision....
