Hello. I bought this truck a few years ago. It didn't have a bed on it (originally had a fuel tank on back, previous owner removed it), so it had a short frame for a 1.5 ton, actually the wheel base is about the same as a 1 ton.
So, I've been looking for a 9 foot bed for it.
I finally found one set up as a trailer on craiglist for a fair price and it was only 15 minutes away.
Anyway, I got it mounted today.
This is a '48-'53 bed and is wider than the 9 foot beds of the '37-'46 series so it's up on 4x6 beams to clear the tires.
Looking locally for '48-'53 fenders.
Here's a link to info about the 9 foot beds, specifically on the featured 1.5 ton -
