Probably, but the stocker is a two row, and you have room for 3 rows in there, so a recore will cure it for sure. IIRC, the tanks are the same shape as a gen1 2.6, which IS a 3row, and you can fit that core to your tanks. Won't work swapping radiators, as the hose connections are different. Look at your bottom radiator header and see if there's a row of dimples there where a 3rd row would go.
