I don't know enough about the 60-66 generation of trucks. I got these yesterday because they looked too nice to end up as scrap metal. Grill #1 is a GMC. Grill #2 and #3 are Chevrolet. All in very clean and straight condition.
$100 ea/BO.

***SOLD***I also have 2 NOS Grill support assemblies. Not sure what years they fit, but I was told they are 64-66***SOLD*** Thanks,

The #2 grill is for a C 40 and bigger truck. I'm not sure just what year it is right now, but I know where there is one I can look at and let you know. My 63 C 60 grill is different, so it's probably a 64-66.

The grill shown in pic #2 is used on a 64 C50 truck. I'm not sure if it is the same for 64-66 with the medium/heavy duty trucks as it is for the light duty trucks. Just FYI
