Suburban is a great model and except for a few parts they use the same parts as other models for 51 and 52.. The rear fender trim is the same used on the fast back cars which is different than the other  models. The tail lights are also different as well as where the wiring goes thru the firewall. I have restored two of these cars because I like their looks and value.

The front end sheet metal from any 1951 or 1952 Plymouth will fit - Concord, Cambridge or Cranbrook - and any body style.  They changed the hood ornament, hood emblem and series nameplates for 1952, but no other changes.
