disk brake kit
this is probably too late to the discussion, but for others thinking of a brake swap. I put '73 a-body BBP disks on my '66 Cuda, and I went with Mustang? painted 14" Magnums. They're different and look good, too. I did this like 25 years ago, so memory is a little fuzzy. I can't remember if there was an issue with the hub, or not, but it wasn't a big deal or I'd remember that.
