Drum To Disk On A 65 Barracada

In the short run, I would stick with the two different size wheels. That's just my personal dislike for virtually any "adaptor" to make stuff fit that wasn't engineered that way. for the longer time frame, I would call the folks that advertise axles in the Mopar magazines (sorry, don't have any handy) You need axles for a 7 1/4" rear with the "large" bolt pattern. I got spectacularly lucky, the previous owner had the 8 1/4" rear axle installed from the same donor that the front disk brake hardware came from. That's what I would recommend, but 8 1/4" A body rear axle assemblies seem to be difficult to locate, as I contemplate my '63 Dart coupe project.
