I recently purchased a '86 C10, 8" fleetside truck. I'm needing a new tailgate and I was surprised to see that 81 and newer is different that '80 and older. Is it a big difference or can an earlier one be made to fit my '86?

To the best of my knowledge the only difference is that the inset stamped in the 81 up is squared on the corners while the older ones are rounded there.

Seems like I read here that the 73 & 74's may have different mounts than the rest - cannot confirm that.

Here's a pic of the rounded example.

They also changed the GM logo position on the tailgate. On older trucks like my ‘75, the GMC or Chevrolet was centered on the tailgate. On later vehicles they have the GMC offset to the left and the Chevrolet offset to the right.

I now have an ‘81 ( or later) box and tailgate on my ‘75 truck. I had to also get fuel filler hoses that work with the doors on the newer box, since the old one had fillers that were visible. Other than that, it’s a direct swap/upgrade.

The hinge trunnions are different sizes between the 2 styles of fleet side tailgates.
