If its a chassis your looking for, (A-body) look at
www.pathfinderchassis.com
They had one of there chassis on display at a show a couple weeks ago and it looked real nice. The whole reason it caught my eye was because they build them for 64-67/68-72 Chevelles and I happen to have a 64 so I had to check into it. I was impressed with the quality and engineering they put into it. They had a LS6 and I believe a T-56 trans if I remember right sitting in it so that also caught my eye. Looked real good.
