The radiator in my Ford 640 appears to be leaking. I need to remove the hood to better access the radiator for inspection, repair, or replacement. It has been years since I had the hood off to replace the gas tank. As I recall, all the bolts, nuts, washers, etc holding the hood were due for replacement. Does anyone happen to know the sizes of the bolt (screws) that I will need to remove the hood, grill, radiator, radiator shroud, etc. The tractor is about 100 miles away with no decent hardware store anywhere close, so I would like to purchase what I need before I go. I know that I will need to purchase the various pads, bumpers, and such from this site.
