ON shift linkage side I show the following numbers........PK 34106676..........I go onto Mymopar.com and I believe it matches early 1970 Cuda or Challenger for bigblock...... this I am pretty sure of.....what I am NOT sure of on same side it says 3013 0178 which i think is specific build date....on opposite side (passengers) I belive is the numbers that probably matches the vin number of car it came from OG155399..........which i might add doesnt match my vin....... :ack:
