First and foremost, make sure your frame rails are in the proper position. I have a copy of a frame chart if you need it. With the fender / door gap established be sure to bolt the fender at the lower rocker, and also to the upper A pillar to set the back of the fender relative to the door. The fender will likely conform up front when you bolt it down up front causing the fender to bow slightly at the wheel opening. Dont just hang the fender loose expecting it to fall into place everywhere, you'll need to firmly attach it to properly set your gaps / alignment. You'll notice as you start bolting the fender down that the gaps will change slightly due to slight bowing and probably cause you to go back and forth tweaking things here and there.
The order I went with on mine was doors to body, fenders to doors, cowl to fenders, hood to cowl, hood to fenders... When working with the fenders also install the headlight buckets, and stone sheild to properly maintain the front fender alignment. Once you get it rough, you can see if you need to tweak anything.
