help with 72 chev front end assembly

[1972BackInBlackC10]

im putting the front end together on my 72 chev and im not sure on the order it goes together. My rad support and fenders are on but are loose, should I line them up and tighten everything before I install the grille?

also not sure if I should put the inner and outer grille together before I put it in the truck and does the front bumper go on last?

basically the truck didn't have the front clip when I got it and I have to put everything on it, iv never done one before so I have no idea what the process or order is. Any help would be greatly appreciated thanks
