After putting a new radiator in the bed of my 46 International and messing with it for 2 months now it is still erratic and overheating, my question is, after looking it over very close I think i can put the original radiator back in it, would have to modify and cut away a few pieces of metal but i think it will fit, Will the old radiator work??? would i have to get it rebuilt to work on a 350?? any comments would help..........this is about to drive me nuts, Thank Bill
