It looks like the truck cleaned up nicely !

The broken tailgate handle is pretty common, at least they are available new.

Mine had the same problem. I went looking for a replacement in the local wrecking yard, but they didn't have any 87's so I snagged a metal one off an 85. I also had to change out the latch the handle connects to and if I remember correctly enlarge a couple of mounting holes a bit. It's not a perfect fit, but it doesn't look out of place, and I doubt I'll ever have to replace it again.
