I just started doing some much needed repairs on my '68 Overlander as well. Polishing, rear end separation, you name it. You can't have too many things going on at once, you know!
Anyway, on my one side of the A/S I noticed it looks like someone went over the outer skin at the wheel well area with another skin!
Has anyone ever heard of doing that??? I'm pretty sure it was to add some sort of strength there as I have some outriggers that need to be replaced...three on that one side! (two partially there, one missing). Someone really botched this up. But 'lo and behold, I will fix it, with help!
I still need to remove a bunch more rivets to find out what's what, but I will be doing work on my wheel well, also, and if there's any more advice...let's hear it! Thanks in advance!!!
