Not sure if anyone has grokked this yet; and to be sure, there are so few originals out there that it's really not a pressing issue.
But.... there ARE the Lindy '64s, and the new Moby '65s, as well as the re-release update from the PL kit now R2.
That said, have seen a few builds of the new R2 Hemi Coronet, and they look better than I am recalling, so mebbe I'll snag one just to see what's in the box.
