I currently use Williams/Bally legs. With the castors out farther then normal, the height will line up perfectly. I have no issues.
There are actually three kicker targets (love these things) target to left of pyramid, target below upper right flipper and target that interacts with the pop bumpers is a kick target.
Make sure all your flasher bulbs work, they integrate nicely with gameplay.
and finally the interlock switch sucks especially trying to dial your game in.
