Mike, it looks like an original radiator but it also looks like the motor is red? Was the motor pulled and repainted at one time? All I'm saying is that from what I see in the parts manual and in the description of the axle packages, the 055 is supposed to be an A/C radiator and a high performance (max cooling) radiator is standard with all the axle packages and should be an 054. It would be interesting to see some broadcast sheets for some GTX's like yours.
