MoPar Brake Upgrade Options?

What I would really like a 13 or 14 inch disk brake kit that uses my '73 and up spindles. The only choice really is Doctor Diff's kit, which isn't a bad choice actually.

Baer sells a bunch of different brake kits for the Mopar disc knuckle. Doctor Diff is also a Baer dealer. I don't know if there is anyone at Baer these days who understands Mopar vehicles but it is worth a call to talk to them. I've used Baer stuff on a lot of different conversions so the stuff exists, but they don't really advertise it much. Here is a shot showing a 13 inch Baer kit on a '68 Valiant. (engine is a 427 incher. That car would go 160 mph!)
