Hey guys I am in the middle of detailing a car of my families, and just found out the threading on my 3.5" backing plate isn`t locking into my G110 v2 anymore. Problem is that I am heading back to college on Friday, and planned to fix this car, as well as my dad`s BMW 530 by then. I`m using this size backing plate with 4" Lake Country pads. Now that the backing plate is messed up, i`m pretty much screwed, unless anyone knows of any places in the Bay Area that carry 3.5" DA backing plates? I live in Pleasanton, CA and am going to Sonoma tomorrow for a car show, so if anything is along the way, I could stop in and get one. Any help would be greatly appreciated. Thanks.
