Got my hands on a brand new set of D568 headers for 67-69 Firebird. Man these things look awesome but I have a 67 GTO so I cant use but passing them on to someone that needs them. They are new never bolted to anything. They include no bolts, gaskets or collectors. Headers only. They are round port, 1-7/8" primaries, 3-1/2" collectors, and ceramic coated. $750 OBO and I can ship for actual shipping costs as well. I'll be a Pontiacs in Pigeon Forge in June if someone wants to meet up and get them.
Thanks!
