A heads up on aftermarket disc kits.

Thanks for the information and I completely understand the situation with the floating v fixed calipers. On my 73 Cuda, I used Mustang rear calipers with Wilwood rotors and hats. In this case, I welded the bracket to the rearend housing. I am building a 69 Ply wagon for a friend and he bought a kit from Summit but it requires Green bearings which he doesn't want, so I have been exploring bolt on kits that do not require Green bearings and there isn't a lot out there, Dr Diff has probably the best kit but he is out of stock, I believe I will manufacture new brackets and weld them to the housing, not a big deal.
