I found this pair of lightly used valve covers.Apparently been sitting in the sellers basement since the 70's.They were installed for a short time however they are clean inside so it was not for long.He was asking $550.00 and I offered $350 and he accepted.$25.00 to mail.These are extremely hard to find here in Canada.Ebay is always a lot more and expensive to ship from USa.I am real pleased with this purchase.
