I need some advice on how to proceed with my exhaust system. I have a Ford muffler with the proper FOMOCO embossed letters that I purchased back in ’79 from the dealer. The problem is that it has an 11/69 date stamped on it. (my car was built in Jan of ’65) Would I be better off with a repro muffler with no writing on it, or go with this NOS muffler that is not date coded correctly? I'm trying to do a trailered concourse car, but I am keeping the date codes correct on all of the parts that have dates. Any thoughts or comments are appreciated.
