I also put the new tailgate on the truck. The old one suffered from the typical bow in the middle, and it was rubbing my rear bumper, which had managed to scratch all of the paint across the back.
The handle was dirty, but no rust on it...
It ended up lining up nicely.
Required one quick bit of trimming to clear the latch on the driver's side.
And like I said it was a good fit, but not perfect.
