I have a 69 Mach 1 (2-V 351W) "H" code single exhaust. I ask Scott Fuller on another thread"Parts For Sale", if He had 2.5" concours correct Exhaust clamps for my application. He said the 2.5" clamp is not made and I might be able to modify a 2.125" saddle clamp so it would work on my 2.5" system. and that would probably be my only option. Yes, I've tried that "modify a 2 1/8 clamp into a 2 1/2 clamp",,,,NOT easy and usually will turn out bad. But, when I show the Mustang, MCA has,a few times marked off for my clamps not being correct...If a person cannot get these clamps(repo preferably), then how can MCA justify marking off points if I can't find them. Having to modify or fabricate these clamps should not be the answer, and in turn shouldn't be counted off for. Yes, I'm sure some of you are thinking," Buy some NOS or originals", but, the price is very steep for "NOS" or originals(IF YOU CAN EVEN FIND THEM IN 2.5"). Anyone have any kind of suggestions?
