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?

5. Cab corner rubber bumper

Thanks, any help is appreciated.
