What disk brake upgrade for a 74 duster, not Wilwood

I'm a huge fan of Wilwood, and have used them many times. I prefer 4 wheel disc brakes as well.

If you want something other than stock up front, but it has to be Mopar, i'd look into Viper Brakes up front.

Check this site out. Cass has a lot of brake kits and options for you to choose from.
