I need a 9"!
If you have a little extra cash get his lca's and phb if you don't already have them. Mine sat slightly further back than the 10 bolt with the stock lca's. It wasn't much and didn't really cause a problem until I put my 28's on.
Big Bird- Good call on the back brace.
I am in the process of going a different route with mine. So mine will be for sale. It is a direct bolt in Moser 9" for a f-body. It is stock width. You will get a BMR anti-roll, BMR torque arm, and cross member. (glide). 35 Spline axles with 5/8 extend wheel studs. It will bolt right it using your stock pan bar, shocks, springs, control arms, etc.... I just don't know how much yet, lol I would consider selling the center section as well. Moser iron case, 3.50 pro gear, spool, and 1350 yoke. I have gone 8.81 @ 155 with this setup. The only reason I am thinking about selling it is to go with a narrowed fab 9"
