Auction is for one Set of NOS GM Return Springs. 1 Inner, and 1 Outer. Will work on most any V8 with a 2 or 4 Barrel. These came several to a box, so you will NOT receive the Box. The plating method used by GM was not the best. The blue outer spring looks good, but the silver didn't stick the best so some are better than others. When only GM works, these are for you. The ebay fitment guide is only a guide, so please make sure this is the right part for you. Winning bidder to add $4.50 shipping with tracking. US only, Paypal only. Thank you for looking, and good luck.
