we had a gleaner k2 gm 250 until last fall and before that a start k with the same motor 1996 with the k2 the rad was recored $506 cdn later it is expensive though consider how old the rad is
The guy I farm with does radiator recoring at his gas station and we soldered around the neck on mine last year with it on the machine, luckily. That much money for a recore sounds unreasonable. He did the recore for my Super M Farmall last winter for 275$, I am sure he discounted it some but still. I'd check around, good luck!
