Gotta make it your own. The chopped Merc is an icon but it's an individual's interpretation of "the Chopped Merc" that gives it individuality. Gotta look at a whole big bunch of them and see where you fit. Lots of material in the ether. I used to think they were all the same. They're not.
I just picked up a '57 300C kit. Makes a nice mild custom. Lots of plain, flat sheet metal. Already has some custom elements going on. Gotta get it down, though. Way down. Built one decades ago, stock version. I recall a severe fit issue. But I digress......?.
