Update: I had the new radiator mounting brackets moved to provide clearance for the fan blade and it fits. It is much longer than the old radiator and it covers the handcrank starter hole but I guess that larger radiator has a benefit. It actually keeps the truck operating tempature cooler than the originial radiator had before. Anyway, it ran for several hours today without over heating. I drove it around most of the afternoon and it was nice to finally get it back on the road. Thanks for all your assistance.
