Of course what works best for one person may not be as good for another. I didn’t have any help and this is the order I did mine.
1. doors- they are needed for fender alignment. It was easier for me to install all the door innards and glass after the doors were hung.
2. inner fenders- I set them in place so I wouldn’t risk scratching anything trying to install them after the fenders.
3. front grill piece- mounted it loosely and slid the radiator support as far forward as possible to make sure I had room for the fenders.
4. fenders- once tightened to the grill, you will need to shim the radiator support, and back fender support to make the rear of the fenders parallel with the front of the doors, and match up to the curved section of the door. Then slide the whole front assembly back towards the doors allowing enough room for the doors to open without scraping the fenders.
5. hood- I did have to enlist some help to put the hood in place. It was just too much for one person.
6. Bed- I assembled it first, then put it on the frame using a hoist. After the bed was in place I loosely mounted the running boards in place, then installed the rear fenders.
Good luck!
