i'm trying to put a rc engineering exhaust on my 76 750k. the headers are set up to use split collars, which i have, but they are about 1 15/32 inside diameter, and the outside diameter of the headers is more like 1 17/32. anybody else run into this by any chance? these collars came off a 77 hondamatic.
also have a junk set of headers with k type ends but would like to avoid cutting and welding.
