Well, I have an electrical issue now, will need to get someone who knows something to help me out.
Meanwhile, I did something that a dummy like me can manage, repairing some of the aluminum trim. One of the tailgate pieces was really messed up, so took off and hammered enough to straighten out. I also put on the taillight trim that I got from this forum.
Removed the original trim, I know it's different looking than what I got.
No surprise the clips look 51 years old. Kept the tailgate one in place.
Inventory of reusable clips, I'm lucky.
I hammered the "new" trim enough to straighten, and steel wool cleaned up.
Some of the threads I read, 3M tape seemed to work, so I'm giving it a shot.
Finished, looks good enough for government work.
