its a 1951
the door has wind wings and the hole for handle is single hole instead of extra hole for the 52-55 handle.
cant be 54-grill is 50-53
cant be 50 since wings didnt happen till 51
so I guess 51 but it MAY be a 52/53
I don't know the year of it, but it looks like something I would find in the swamps here in North Florida (wait a minute, are those cypress knots over to the far left?)
think it may be 53 or 54
I love rat rods and my 37 1/2 chevy fendered has been one since 1977.A good grill still looks good even in a rat IMO..This GMC has a good grill and looks like well worth saving for a fun rat.
