I have a cloner 65 SS... originally 194 ci Nova 400, now it's a obvious fake SS 327 PG (and it will become a M20 in the next few years). I never tried to make it an accurate clone... just picked the SS parts I liked (Interior, cove molding), and left off the stuff I didn't like or couldn't afford (rocker moldings).
Real 65 SS cars seem to be a rare breed. I know one is gone... sent one to the crusher about 15 years ago... it was REALLY, REALLY rough. I saw another in a junkyard back in '96, but it was completely picked over.
