No UPS vans had the five bar Grumman grilles.
Chevy Dubl-Duti I think 1938 or 1939 on the GMC and then Chevy I have to look that up. I like the 1940-46 Dubl-Duti.Yes the lady said that It is a Chevrolet I think a 1967 Grumman.
will have to wait till the new photos are posted. My 52 GMC Grumman was made with the Chevrolet marker lights I was told by a old timer that if they ran out of parts you got what was left in the storeroom at the time
