55.2-59 Front grill/accessory install order

[Missyblue]

Hello! I am trying to put my front end completely together and I keep taking 1 thing off 3x after I learn something else goes 1st haha. I had to tear out my radiator and mustache again because my power steering pump blew a leak 😭 think I am down to the fender wings that attach to the lower radiator, the bumper fill panel, bumper and bumper bullets.....any tips on the best way to do things? I currently have to pull my mustache for the 3rd rime to put the grill in first haha. I was waiting to put it on last since I have been doing wiring and lights and hadn't worried about it yet oops. I have a gmc 1957 with the 1 year grill......thanks!!!
