1970 Road Runner
As said above, there should be no question unless the VIN has been tampered with. "RM23VOA.........." The "V" means one thing..............440 six barrel. Other things in the fender code. If it's a 4 speed car it should have the Dana 60 rear end, my understanding is that some auto cars came with either Dana or Mopar 8 3/4
Google "Mopar VIN decoder" for info
Is this supposed to be an original Road Runner body, or a "clone" IE Satellite converted?
