Thanks Matt, I was just looking at a table of rear end widths and my thought is I need a rear end in the 54" width area.
The models you mentioned (thanks) are still going to be a to wide. The leafs have already been moved to the inside of the frame to accomadate the 295s in the rear but I'd like the rear wheels to line up (laterally) with the front wheels...you know what I mean?

Thanks for the comments on the car. I picked her up a few months ago and so far have rebuilt the front end, switched out the drums for discs in the front, and went to power brakes with dual resevoir.
