68 Camaro, adjusting front end

[Vidar]

Hello

Cant find any "how to" on the easyest way to adjust my new front end.. Having problems getting everything ok. BIG problems.
Seems like the fenders is for another car :) Doors are the old one, but have been repaired for rust. They fit good, but the fenders dont. Seems like they dont have the same curve against the door

start with the rear of the door opening. make sure its as close to the factory dimensions as you can, install the doors and line them up with the rear of the opening and along the bottom, get the gaps correct. check door operation, if all is good here move to the fenders, using the leading edge of the door to work with install the fender using enough shims to get the bolts in place and get them snug. take a good look at fitment, adjust shims 1 bolt at a time. it'll get there, slowly.
