1964 Dart restoration start
Classic Industries doesn't carry a whole lot of parts for these cars. I have spent oer a year looking for everything to get mine restored and I just recently gave up and decided to trade it off to a guy in Austin TX for a 47 Jeep CJ2A with the original flathead motor and trans. The taillights will run around $500 for a pair I may be able to help you out with the front grille the guy trading for mine is only wanting the trans and a few other parts, but he decided to take the whole car cause I'm tired of looking at it. Oh and the interior will run you over a thousand for everything.
I wish you the best of luck with your restoration and you can always check out slant6.org as well, people tend to sell off parts for these on there as well.
