Please help me with sequence of front sheet metal install.

[prostreetC-10]

Well it's getting time to get the front end back on the beast. Problem is when I pulled the parts off, I ran into some clearance problems but I'll be darned if I can remember where. I know I pulled the fenders and fender wells off together. I believe the front core support was still on and made it a beach to get the fenders off. In a perfect world, how should this stuff go on so I'm not scratching what I just painted. Should I put the fender wells on and then the fenders as apposed to as a unit? Figured some of your truck parting pros could help. Thanks guys!
