I am in the process of rebuilding my suspension. I had to torch off my control arm bolts because they were all froze and now I need to get some replacements. I know these are a very high grade bolt and not a very common item in hardware stores. Does anyone have an idea of where I could get these or what size and grade bolt they are? Thanks for your help.

Hi Josh, Front and rear lower control arm bolts are M12 X 1.75 X 89 GM P/N 11514112 washer for M12 GM P/N 473539 nut hex M12 X 1.75 GM P/N 11502813 These GM part numbers are from 1990 and I don't know if they are still valid. -Robert 87 GT
