Please Help Identify This GMC Medium Duty

[special-K]

That's right on the emblems. The same holds true on '67 light duties. The GMC with series under it began use in '68. Up to a 6500 can be a medium duty. The Cs, Es, and Hs Blend and intertwine in that grey area. Not sure what you know so far about the VIN, but E is the chassis type (like C and K), M is the V6, and 5 is the GVW range (5500). The rest varies from light duties in those, by my reference. That's a neat truck. So, it's a flatbed with a dry goods box mounted on top, or is it just hauling that?

I wasn't aware that the early ones had no emblems.

Good eye, Tim. I didn't even notice that. Looks like it also has a Hydraulic Gate on the back as well.

That's the only way I know one is a 66 or 67. You mentioned something about turn signal locations telling what year. What are the differences there?

Yeah, I noticed the gate on the rear,too. I wonder if the truck is set-up to adapt either way or if the box is just there to transport? It's not strapped, so must be bolted
