I have a 292 in a 59 1 ton. If its a half ton then get the Langdon's Stovebolt 292 mounts. They are welded in and work fine (but I had to modify them to work on my 59 - 1 ton frame is bigger). You don't move the radiator, but you might have to play with fan spacers, and you use the 292 bell housing with your old transmission - it bolts right up. Sometimes you need a water pump with a shorter shaft on it, but I didn't need it. You might have to customize a radiator shroud to work with the fan.
