My legs look pretty bad, and I'm confused (normal for me). My existing legs are 25" non-ribbed on the front, and 28.5" ribbed on the back, and they look painted, not plated. PBR says 31" painted legs all the way around. If I go that way, I'll struggle to get much pitch on the playfield. I have the back legs all the way up now, and the front levelers all the way down. Can anyone steer me to the correct legs for this machine?
