70 Bell Drum question
This is a problem because? Won't you still have 5 nuts holding the drum in place and a wheel to cover the ugly? Never said it would be Mopar perfect, just said it would work. I agree that the perfect solution would be a conversion to big bolt pattern, but what if dustadude doesn't have the bucks or inclination for new axles, front spindles,upper control arms, dust shields, rotors, caliper brackets, calipers, pads, hardware, bearings. etc., AND the aforementioned rear brakes?
This is a problem because the wheel studs do not fill the hole in the drum and therefore the drum may not be centered on the brake shoes. Even if you get it close there will be premature wear on the drum and the brake shoes as the drum runs off center. That is the reason they didn't use the same bbp 1 3/4" drum that is used on the mid 60s B bodies. Under your thoughts they would have only made one casting and drilled it for each pattern.
If dustadude has a 7 1/4" rear end all of the disc brake A-bodies from 1973 through 1976 have big bolt pattern rear ends and a 7 1/4" can usually be had pretty cheap. It also will bolt in without any modification. In 73 through 76 there was also an 8 1/4" rear end available and only the drive shaft and shock plates have to be changed to use it.
Getting bbp on the front end would be the more expensive part. Upper control arms have adapter bushings that are available from doctordiff. There is still lots of disc brake parts out there for a conversion. Right here in my town there is a set up getting ready to go to the crusher this week. I am not up to pulling them before he hauls the car off.
Here's a list of all the Mopars that use the same 10.98" rotor. You can also pull spindles and calipers off of any of these cars. Some will have pin type calipers, but if you grab everything from the spindle out you'll get the right caliper brackets. Some of them also had the 11.75" rotors from '76 to '81.
