I just finished putting my 53 3100 front sheet back togeather. I determined that the radiator support should go in last. Just hang the inner fender aprons on the cab, just start all the bolts by hand, then hang the fenders on the aprons, again leave bolts loose. The hardest part is getting grille, aprons and fenders lined up, especially if the truck has been wrecked. I madeup some "alignment" pins to hold things till I could get the bolts started. Keep in mind that the braces that go from the cowl to aprons will hold the fenders in place, now the radiator support can be put in, again leave bolts loose. If your fenders, grille, and support are aligned the hood should fit "good" none of them fit perfect. The "key" is take your time and have a good "helper". I hope I have been of some help.
Phil.
