The Stovebolt Site Forums The Shop Area General Truck Talk Need Help! ID '60, '61, '62, '63 C10

I've got a '62 Suburban.
I liked the '60 and '61 quad headlight grilles better, and found one.
On Dynacorn's website, they list different radiator core supports for '60/'61, '62 and I think '63.
Now, in a local junkyard here, there is a truck I parted out that has the knee-knocker cab ('60-'63). It didn't have the grille when I got to it, and the little data plate on the driver's side kick panel was missing.
How can I ID that truck, to see if I should grab the core support from it to mount the '60 grille in my '62?

Thanks,
-Brad
