My M715 Radiator is just starting a very small leak. I want to find a NOS one or a place to find a reasonable same replacement. I don't have to do it immediately but will if one can be found. The problem is I don't want to put one in if it limits use with a different eng. swap in the future. What if any engines that usually go in the M715 will work with the original radiator and does anyone know the best place to get one? I prefer putting the original for now so I can do other vehicle upgrades, Brakes, steering, etc. you know so I can drive it right away.
