Please help me identify my truck!

[turnjare]

Hi everyone. I’m looking for some help identifying my truck. I’ve already decoded my VIN number as well as the Engine number, but I’m still left with some questions.

The VIN number is 5GRB2747. This number is for a 1949 3600. It has 8 lugs on each wheel, a 125 inch wheelbase, and is a split front window truck. The problem is that the gas tank is mounted under the bed instead of behind the seat. Also, I read that the weather stripping around the doors should be mounted in a channel and mine are screwed down with a metal strip. The rear of my cab is mounted to the chassis in the center and has rubber bumpers on the cab corners. The VIN plate on the cab seems loose, like it may have been replaced. Is that possible? If so, how do I find out what truck I actually have?

Pictures:

2.VIN tag
3. 3 window body
4. Screwed down weather stripping
5. Cab corner rubber bumper

Thanks, any help is appreciated.

Looks to me like a 49 stake body, some had under bed tanks and all 49's should have center cab mounts. Weather stripping I wouldn't worry about but the ones I have seen did have a channel. You can get the channel if you need to replace the stripping. Generally the VIN plates are gone not just loose.

Based on the ventless doors and the handles it is a 49 like mine. The PO could have moved the tank themselves back in the day so they could throw stuff behind the seat. From the sound of the 8 bolt and the 3600 on the hood it is a 3/4 ton truck. But then again it has shortened running boards like my 2.5 ton truck does. so it might be a Frankenstein 49

From what I've found early production 49's had a center cab mount and screw on wind lace mounting. Some time about August of that year depending on the production plant, the cab mounts were changed to the shackle style and the wind lace mounting was changed to a channel. I understand that the in cab tank was only on the pickups. The cab - chassis models for flat beds, dumps etc all had frame mounted tanks.

it will tell you all you need to know about your truck. Short boards were on all stake bodies. The tank would be under bed on a center mount cab. The mount would be in the way of the tank in the cab

I think Nvrdone most likely hit it exactly on the head. Early 49 truck. Along with the center mount on the back of the cab there should be an inner panel all around the inside of the back of the cab behind the seat that reinforces it. The trucks with gas tanks behind the seat don't have that panel. The running board looks to have the folded over lip that the running boards made for flatbed trucks have.

What are the plans for it?

Thank you to everyone for all the replies so far. I was confused because I had been reading about all of the changes that were made in 1949 that my truck didn't seem to have. The VIN tag dates this truck to Feb 1949, so improvements that happened in August 1949 would not have been introduced yet. It all makes sense now. For starters I"ll keep working on getting it running. This is my first ever project so I'm pretty clueless. I picked an older truck because I thought it would be easier to figure out a simpler machine.
