If you have an automotive paint supply shop around they can usually match to the inside of the cowl or some other non faded area if you have one. I am not sure about he hammer tone finish if it is textured however (not familiar with that model)
I have had good luck with DuPont nasson automotive paint. You can get the self etching primer, base, catalyst, clear all under nasson name. Reasonably priced. Some Napa’s and o’rielley auto parts stores sell it, but always got mine from a paint shop.
