I am on my 3rd restore and dont use rotisseries. When disassembling the bottom playfield it is best to make sure everything is disconnected and then simply slide it over from the playfield onto a large piece of cardboard. This way you maintain the wire shape memory and mechanism placements much easier than a pile of spaghetti on a work bench!
I like to do all of my upgrades, switch-outs, wire cleaning, new wire ties, etc. with the wire loom in this position and when all done simply slide it back onto the playfield when its ready. I have done it this way both times and it makes it a snap. The wires are like a road map and basically go right back where they should by themselves. Flip the playfield and start on the top. I sit mine on a couple of sets of standard bricks and bubble wrap cushion. Seems to me you would have to attach the majority of the bottom playfield wires & assemblies before you flip it on a rotisserie anyway to keep things from flopping around and straining wires. I think the majority of playfield swaps are done without "rotties" but hey...to each his own.
