There is a lot of work to be done, but just vacuuming off the playfield made some difference.
My playfield service is still just in the early stages until the electronics are at 100%, so check back.
The new and old: Because there was no playfield glass on the game sitting in a garage for probably years, many parts have surface rust on them. Some can be repaired but with these wire lane guides its just easier to fashion new ones. After getting some stainless steel welding rod from a local welding supply store, I bent it to match the old one then cut. I fits perfectly into the holes for the old one. I also got some thinner wire to replace the ones that stick through the playfield from the leaf switches on the underside.
Which is the original, and which ,
the one I made with some plyers?
The bottom one is my fabrication
