need help verifiying 1972 RR H code car
 

does anyone know if hawke chrysler plymouth is still in business in tampa fla. i bought a 72 rr h code 4spd car. it was orinially sold from there. i cant find the original owners name either. thought that maybe a start. The car is optioned out really weird. Of course the buildsheet is long gone. optioned out as a RR/GTX,H code car, a/c, pwr stg, pwr disc brakes, 355 sure grip, tuff wheel, just to list a few, all matches fender tag, but the gtx package would only be on the buildsheet, this car may have had two buildsheets. can anyone help? I thought that only engine for 1972 gtx packaged carswas the 440?
