Call Firm Feel and tell them what you want to do and get a recommendation. I believe the B body sway bar is what you want to go with using the offset hangers and B body rear (assuming the B-body leaf spring mounting pad to pad width, but call and see if they verify.

Or you could spend the same amount of money on and E body bar, bend it all up, find out that it won't fit with your brake calipers, try to return the bent and scratched up bar, find out you can't return it, end up making some whacked out S curve looking end links, be not happy that they don't look remotely stock, find out they also deflect force outward on the sway bar and side load bushings, finally end up calling g Firm Feel and getting a recommendation for a bar that will work like you want, spend the cost of a new sway bar again.
