Found a good local deal on a solid 69 Coronet four door (gonna use it for parts). Does anyone know if the front frame rails & torsion bar crossmember are the same as those on a 68 Charger ? Also, are the rear frame rails the same as those on a 70 charger ? The two Chargers are mostly complete ( 70 still runs) and I would like to possibly get them back on the street. Any input would be greatly appreciated.
