I was thinking of coming over my t-case and then coming into a single exhaust. And for my column, I was planning on finding a 4 speed detent plate.

I used the original big block manifolds from the 91 Suburban and the exhaust shop did the rest. You can reuse the original column and use overdrive as D, Drive as 2ND, 2ND and third gear. I also used the 4L80E in my truck and it works great. Here are some pictures of the exhaust, hope they help.
