Did you look at any of the components on the firewall? They may at least tell you which maker it comes from, AC Delco = GM, Autolite = Ford, Mopar = Chrysler, etc. I'm guessing from that mangled rear fender that it is a Dodge or Plymouth of the early '50s.
Is that a removable rear fender ? Looks like a gas filler in the fender too. At least the car had a nice colour blue once.
Chrysler desoto and dodge came with wheel studs plymouth had wheel bolts..........also mopar loved the 3 piece bumpers. Looks like a ball and trunion driveshaft.... I'm going to say due to lack of rear door, small trunk lid and no rear vent window it's a 46-48 plymouth 2 door sedan.
Looks like a Dodge D24. Possibly a Desoto or Chrysler of that vintage. Plymouth P15s didn't have the sway bar/panhard bar at the rear axle.
