I wonder when was the last year those VIN plate holes were punched?
Could it be that the first location ended up being a bad spot and the plates would vibrate over time and fall off or the rivets were weak?
I see they got moved to the top part of the cab later on. Rivets on mine look cheap compared to the rosette style.
My 61 Suburban only has the kick panel plate. The two holes in the front pillar look clean and unused, but the truck did have a cheap repaint in it's past.
I'm the 3rd owner and the 2nd owner gave me original owner's old receipts and registration from 1975 showing it as 1961 model year. I have repair receipts going back as far as 1970 with the original owners name, listing it as a 1961.
First thing I tried to find was build sheet but no dice. I even looked on top of the gas tank. The original owner is still alive (89y.o., I think ) and I tried to call him but nobody picked up.
Either way 60 or 61 is all good with me
