Cool build, Here is a similar project that has not been finished. Might get some ideas from this guy.

He went from a 2wd to a 4wd but it looks like yours is quite low, you did say in the first post that it is a 4x4 Tahoe so is this staying 4x? kind of confused me there.
I have to ask the dumb question on the Porsche.. How does the trans drive the rear wheels if the drivetrain is in backwards? Or is it front wheel drive?
You clearly have some fine skill so I am sure this will be a clean conversion. Keep up the good work.
