Can anyone tell me what i need to do to get this door aligned better? It hits on the top.left and catches the fender down low when you open it.

Is the door aftermarket? I think the window frame needs to be moved.

Maybe you need to move the bottom of the fender forward to make more room for your door.

definitely an OEM door. I think the fender is as far forward as possible.

Not by looking at the gaps in the picture it's not.. The fender is too low in the front or the cab is sagging in the rear.. How does the cab contour "bump" at the rear corner line up with that line on the bed??.. Probably the cab mount rubber cushions and also the ones on the core support are sagging.. Replace those six mounts and realign the fender.. If need be, you can slot bolt holes and move things around....

Mine was the same way.. I replaced all the mounts and everything lined up nicely..

Ha, the cab is in sad shape, so yeah, that could definitely be part of the problem that i hadnt thought of.

First, you gotta get the cab mount "footings" squared away.. Maybe the floor also.. They're channel shaped and bad about collecting dirt and moisture and rotting out. Replace the rubber cushions and related hardware. If the cab doesn't sit right, you'll probably never get the fenders to fit right. You should also replace the rubber mounts on the core support.. Then align the door in the opening.. Last is the fender.. You don't move the door to align with the fender.. It's just the opposite.. Align the door to the cab and then align the fender to the door..

Have a look at the core support bushings too..

Ok, turns out out the core support is completely rotten, as in the mount on the passenger side is rotten though. The mount is doing nothing. Obviously, if that were as it should be, the core support would sit about 1/2 to 3/4 of an inch higher, thus separating the fender from the door on the lower front of the door.

It's common for the passenger side of the core support to rot out.. The main cause is over the years, leaking battery acid gets to it.. Looks like it's time for some serious restoration work to begin.. Core supports, cab supports, floor patch panels, frame brackets, rubber mounts ------ all are readily available...
