Is anybody using hedman 88300 headers on a 4 speed car? I want to use these but would like to know if anybody else knows if they will fit or not. The website says that they will work for mustangs (64-70) with a manual trans but not in a maverick with a manual trans. Wouldn't the z-bar go thru the header in the same location no matter what car it is in since the mount is on the block. Stephen
