Guess it depends on where you go - I ordered something from Hunter Holden in Australia and got it in less than two weeks.
Oh, and American Axle is on strike - which makes alot of parts for GM’s trucks, as well as some smaller brake & spindle components. The GM-proper factories on strike are ones building Lambda crossovers (Enclave/Outlook/Acadia), and one of GM’s Epsilon (Malibu, Aura) plants.
