The Stovebolt Site Forums The Shop Area General Truck Talk 57 Chevy 3600 vin question.

So not sure if this is the right place for this.

I took a look at the plate on the driver side with the VIN and found some numbers and letters, and tried to figure out what they mean, tried using Google as well but no luck.

So can anyone of you guys help me out?

Here are the numbers

57 3600 SAJ31906
5800 LBS
2500 LBS
5000 LBS
