Quoted from RoadQueen:I’m newish to pinball owning too and Cliffy scoop installing also seemed scary initially but was not bad at all. Follow key posts from Vitty and Fooflighter for photos and steps. BUT, I did not disconnect a single cable or cut any zip ties. So after removing the 4 screws that hold the upper playfield just had enough room to carefully lift it, slide a microfiber towel to avoid scratching stuff and it gave me enough room to work on the scoop. Best thing was to lay all the removed pieces and nuts/bolts in a straight line to be able to track my steps back to put it back together, and take a photo before disassembling each step so you remember how to put it back.
I had the same experience
