It's not too bad. If you flip up the playfield you will see the mech for the scoop. IIRC, there are 4 hex screws holding the mech to the PF. Unscrew, move the mech out of the way, install the mantis protector (with said 2 screws) and reinstall the scoop mech. Took me about 20 mins or so. You'll have to push some wiring out of the way,possibly disconnect a harness or two, and you may have to have an extension or a long hex driver, but you shouldn't have to take off anything on the topside.

mrgregb123 Hoping that Mantis can come up with a scoop protector for the SIM card hole too!

I don't recall having to move the subway. The subway feeds into the scoop. You shouldn't have to drill pilot holes.. Just a bit of pressure on the screw while twisting is enough for the screw to bite into the wood, though it's not a bad idea to drill small dimples. Like I mentioned, you'll have to move some wires out of the way, but you shouldn't have to do much more than that to get the scoop out.
