Hi All,

Tried the "search" for this, but couldn't get an answer so I thought I'd throw it out there. I'm working on bringing a '51 GMC 100 back to life and it looks like I'll have to replace the temperature gauge. Figured I'd redo all the gauge faces while I'm in there. Looking in the various parts supplier catalogs I've got seems to indicate that the gauge faces for a '51 GMC 1/2 ton should be cream or tan with red needles. What I've got is brown with white needles. The parts suppliers apparently identify this as a '52 (although the pictures seem to show the ammeter with "D" and "C" instead of "-50" and "+50" like mine has). My speedo is also brown with a white needle. Is it possible that '52 gauge clusters would have been used in a '51 truck if it was made in March of '51? Did they use both colors at some time in '51? BTW, I'm positive that the truck is a '51 (got the original bill of sale from the dealership dated March '51). What gives here? In the mean time, I guess I'll go with the '52 temperature gauge and call it good.
