BBP Front Drums

I don’t know where you can find a set right off, but I have a friend that has a set that is installed onto a 1965 Valiant that came off of a 1974 manual brake A body along with the spindles and upper control with larger ball joint. I imagine that there are several 10 or 11 inch B body drum brakes that would work doing the same thing. I don’t think that there any factory front drums with large bolt pattern that fit onto the small bolt pattern spindle. @72bluNblu probably has some more in depth knowledge on the subject.
