Yours came out really nice where as when I tried to restore my right headlight the yellowing was on the inside. So for ease and not wanting to try and split my lens and housing I just replaced it, $20 for a TYC from Rock Auto made the decision so much easier. The original owner of my truck chose to replace the driver side because of yellowing, adding in my headlight adjusters were cracked and froze I chose to replace it all rather than fight with it.
From what yours looked like, from your pictures and details from when you got it, yours has gotten some serious love also.
I'm interested in seeing your truck evolve.
As I was replacing the passenger side head light I came across some tattletale signs that that corner, passenger side, has been fixed/repainted. There was body color paint on the adjusters for that corner, from the factory there wouldn't be any, which means at the minimum this corner of the truck was repainted... Kinda bummed because I was hoping it was factory paint but on the bright side though, the original owner took good care of it.
