For those of you unsure if you have ab LCF truck one sure way to tell is, "Is it a Chevrolet?" Only Chevy used that name. GMC did build a "Short Convertional" it was the F-model for 1955-1959, and the B-Model For 1960-1966.

Here are two pics were you can tell if you have one of the Short Convertional trucks:

1955-1959 Chevy LCF & GMC F-Model Trucks

1960-1966 Chevrolet LCF Trucks

This is the Truck GMC Built in the 60 that was the brother to the Chevy LCF, the GMC B-Model , That should help with the ID of your trucks.

Now for Ratings, A lot of guys call these trucks 2 ton or 5 ton or some thing like that, I never really liked that system, as most 2 tons can haul a lot more than 2 tons. If your truck is rated for 19,500 lbs (like My LCF), and a lot of them are, that is 9-3/4 tons. My truck being an L60 tips the sales at 5270 lbs, add another 2000 for a bed, that would be 7270, that 3.635 tons, which leaves a little over 6 tons for payload, and most would call a 60 series a 2 ton.
