I replaced the tank on my '63 Dart wagon with a tank out of a '63 Valiant ragtop and it went straight in - the one out of my '65 Dart 4dr parts car looks identical too.
thanks. i looked on rockauto.com. they list two different part numbers. same dimensions and they look identical. the one for the 63 comes with a grommet. the one for the 64 doeasnt. only about 150 bucks. not bad. thatnks again for the reply.
When I put a new tank in my car, I found out the difference. I'm having a brain fart. I was dealing with Dante's and we both........crap. If I'm not mistaken it had to do with the size of the inlet hole in the tank.
