Goodevening to all who are out there!! I'm looking at a 1953 Chevy Panel Truck That has factory installed glass on the sides much like a Suburban, but the glass is fixed and appears to use the same type of window channel rubber as the windshield. The truck is totally original as the current owners father bought it back in 1953 for his plumbing business. I have seen side glass similar to this installation on long wheel base school buses.Is it more valuable like this,as a rare model work van or is it worth less because it's basically a panel with holes cut in the sides? By the way, it's a short wheel base 1/2 ton. Thanks, Steve
