Hi guy's, I bought a couple of these emblems about 20 years ago but now I can't find them any more.
I'm pretty sure the emblem was made by a company in California named ACSCO because the 351C emblem looks remarkably like the 427 Cobra emblem they display in the gallery section of their website.
I have emailed ACSCO several times and they are unable or unwilling to respond.
A web search revealed a couple of Mustang parts suppliers that show them in their website catalog but when I contact them the answer is "out of stock and no backorder". Anybody out there got any ideas or perhaps maybe even a contact at ACSCO. I figure with new blocks being produced maybe somebody can get ACSCO to make a run of these emblems.
