I agree with Carl about loosely bolting inner and outer fenders together. You might also consider bolting radiator support, fender supports, etc together and install the whole front clip as a unit. It would save a lot of crawling around on the ground if you have a non-scratch surface you can put them on (lawn, blanket, etc.) upside down and get all the bolts started. I fought with quite a few bolts to get them aligned, and actually left a couple out. I have taken the front clip off as a unit after tightening all the bolts and it comes off/on nicely if picked from the two brackets for the fender braces to the firewall.
