1934 Pierce Arrow grille

I put mine back together a couple years ago and think I remember how I did it. What problems are you having? I reinstalled the control arms onto the louvers of each side first with the special shoulder rivets, making unwieldy assemblies of each side. Of course important to get the control arms attached to the correct louver in the correct position to attach the actuation arms. The outer louvers of course step down in length. I used electrical tape across bottom and top of the louvers to keep them manageable and the pins in approximate position. I don’t recall for sure but I think I just put one screw loose on each side connecting the arm of the piece that has the upper pin sockets and mechanism to the side plate (connected to the lower “beard”. This let’s the upper piece move and rotate up a bit to give some clearance to drop the upper pins into their sockets. I put the taped louvers into the bottom sockets first then worked the upper pins in, all one by one and of course there is a lot of back and forth as pins drop out while monkeying around getting another pin in next to it.
