From the photo, that looks like a great Fury wagon. I can tell you personally that sticking with "strictly stock" disc brake set-up is an expensive/exhaustive proposition for a '66 - '68 C-body. From Budd calipers, to rotors, to those $#*& D-10 pads, it isn't easy. I have managed to stockpile a few replacements for what I have, but it has taken YEARS to find, and I started ages ago when parts weren't so expensive. Good luck with the conversion project, and feel free to post photos. Can anyone tell me what BB wagon stands for?
