Hey Paul
I found that Jim Carter Truck parts sells stickers for fixing the face of the gauges, here is a link to the ones you would need for your gauges for the chev.

If the link does not work just go to the website and select 1936-1936, then cab parts, you may also be able to look under decals but I have not checked that yet.
