RBs36- The only vendor I could find listing a 1936-39 GMC 0-80lb oil pressure gauge is Jim Carter PN: RESP285 which is a combination Amp meter on top and oil pressure on the bottom unit. However it's currently listed as "Out of Stock". frown Don't know if they would be able to help you with just the oil pressure gauge, so you may need to talk to them directly.

If no luck with that route, you may have to resort to an add-on under dash gauge to monitor your oil pressure.



John - Here are two of our usual vendors that offer higher pressure reproduction 0-60 psi oil pressure gauges for 1940-46 Chevy trucks:

The Filling Station SA-496

Jim Carter SP234
