Fisher Body tag question for all the experts

[robber6910]

I have a 69 Camaro. I am unsure of which model I have due to the fact it has the X44 code. I have spoken with several other individuals and most of them are split on whether I have a regular base Camaro or possibly a COPO. Is there any other ID tags on the car that can help me tell which model I have? The engine in the car is non-matching numbers 350 (the previous owner had it setup for drag racing) and the rear end was changed out for a 10 bolt posi. I have the correct BB heater in the engine compartment (located next to the right fender), with both hoses coming out of the middle of the heater. The car also has the original BB radiator (5 row). The Fisher body tag on the firewall contains the following info:

ST69 12437 NOR239856BDY
TR 711 53 BPNT
01C X44

VIN# 124379N584302

From what I was told, the car was built late in 69 (January if I remember correct). My DMV (New York doesn't have the history of registration due to a fire back in 1990 that destroyed all the microfishe). There are too many discrepancies on what I have. All help is deeply appreciated. Thanks
