Bill, I don't currently have the correct radiator for the truck. I have a big truck radiator that came with my 1940 GMC military truck that I am using the front clip off of. It is 3 or so inches thick vs whatever the original radiator was and it also includes a fan shroud. HOPEFULLY it will fit if I use the 261. If I end up going the 228 etc route, it may not and I may need to get an aftermarket radiator that is thinner. I could also always go the electric fan route but I would prefer to keep a more original look.
