SOOOO after 4x days of trying to find drum brake swap parts for my 02 Silvy, I finally called GM ( womp woommpp wahhhhhhh ) I have a good GM number for drum backing plates GM#15911567. Those effffr's go anywhere form $92-$15x ....WTF!!!!! Thats a joke. Anyone want to swap their drums to disc or have a spare set of drum backing plates? I'm open to trades as well, lol
