Well, I have a Demon and an A body 8 3/4 too - I was planning on putting the A 83/4 in the Demon, but I can just as easily save that for the Dart if my B 8 3/4 will go in without a lot of problems. I guess the easiest thing for me to do is just get out there and do some measuring. The Dart will be mini tubbed w/ a relocation kit - the Demon will just have offset hangers/shackles.
