The springs were made by Counterpart Automotive in Taiwan and I bought them from the Truck Shop in CA. Due to the time delay and scratched parts I never contacted Truck Shop about this. I have recieved Counterpart's parts from Chevy Duty as well. I'm sure they supply everyone. I emailed Classic Industries and was told their hood springs were made by Counterpart. I saw an NOS spring on Ebay once, I'll have to cross my fingers there will be more.
