Hi yonkiman. Nice of you to help a friend! I took some pics of my RK. I couldn't find where to buy the part that's missing, but I took some pics of that, too. I have more pics if these don't help. If it helps, the switch arm is 1-1/8" to the first bend. Then 1/2", then back down 1/4", then 1/4" straight again. However, this switch only has 2 posts. The only ones I saw all have 3 posts.
There's a pic of the ramp. As long as the ramp is out, you should take a look at the end where the ball drains to the left kicker. That end gets beat up pretty good. I used A&B epoxy putty and then sanded it down. It makes for some good fortification for a $99 part.
I hope this helps!! Let me know if you need any more pics of the wiring and switches.
I included a couple pics of my machine when I got it and when I was finished. (I just wanted to show my work)
Check it out!!
