Are you talking about wjrwolfe? If so, nice guy, good parts, fair prices. He's an old Mopar man from way back, master mechanic, rebuilds motors, etc. in a nice big garage out in Ault near where I live. I bought a pair of those a-body axels from him last year and they worked great for me. I believe the issues you are referring to involve the emergengy brakes. I used 11" c-bod brakes, and had to re-work the pass side a bit in order for the Duster's cables to work correctly. Nothing major, just machined a bit out of the crosspiece and ground about a 1/4" off the back lever. May be the same issue for the 10" brakes.
