For Sale is one NOS AC Delco Oil cap with S-Rivet, that twists in the valve cover. Fits all 1965 to 1970 Chevrolets with a 350/396/400/402/427/454 Engines and maybe more. Will also fit on the original aluminum finned LT1 Valve Covers for 1969 & 1970. This cap is very nice. This was purchased from a GM dealer. When only GM works, this is for you. The ebay fitment guide is ONLY a guide, and sometimes wrong, so please make sure this part is right for you. US only, Paypal only. Thank you for looking, and good luck!
