There is probably a tread on this already.  Please advice if there is one and I can read through it.

I am going to convert my 71 Cuda from front drum to disc brakes.  Has anyone had luck with the aftermarket units that use the existing stock drum spindles?  There are some kits out there that use 11" rotors.  Any help/advise is appreciated, thanks!

My Wilwood brakes use factory drum spindles. They seem to work well, but I would prefer a sliding caliper.

I believe the Dr. Diff kits use replacement spindles not the factory drum spindles.

I'm not sure if any company has a kit using stock drum spindles and Mopar rotors and calipers?

I think Scarebird uses the stock drum spindles with mixed brand rotors and calipers.

You may be right.  This page lists a Kit A that fits drum knuckles, but there is no Kit A in the ordering radio buttons at the top.  Maybe the drum option has been discontinued and website not updated?  Best to call Cass.
