if it help's my alf 500 pumper lettered for asbury park nj fd is numbered 312, stamped on the box.i didn't know if this was the model number or the 312'th piece of this model produced.now i see it must be the model number.

Joey,
It's the model number; seems to have been realised in generic model with same number.
And about your GMC TASC yes I never saw other kit from DMC.
