The Stovebolt Site Forums The Shop Area General Truck Talk 1955 2nd series - Is it a Chevrolet or a GMC?

Hi,
I have title to a 55 second series Chevrolet truck. I have heard a couple guys talk about my truck and they said it was a GMC and not a Chevrolet. I overheard them say that the cab was a GMC. Can someone tell me the difference between a Chevrolet and a GMC cab. My cab is a "big window" cab. Thanks again for your help in advance.

The GMC cab for second series has round gauges where the Chevy has a single triangular shaped cluster above the steering column. That's one obvious difference I can think of.

The main difference in the cab is the dashboard. The Chevrolet has a V shaped geage cluster , with the Ammeter, Gas, Temp, and Oil gauges across the top of the V. The GMC has a more or less rectangular gauge cluster, with all of the gauges being circular and set in a die cast panel. There are some other differences in the shape of the dash due to the differences in the guage clusters, plus the GMC would have a provision for a radiator core support brace that is not present on the Chevrolet (exept Suburban/Panels) on the firewall.
