I went with the original colors for the rubbers (Titan). Except maybe the flipper, not sure, but went with yellow. Post sleeves are all yellow except the one between the juggler and the ferris wheel, that one is a dark blue.
Machine has full LEDs, but they were all put in prior to me owning the machine. So not familiar with the difficulty of getting to some of them. Luckily they were most white for the GI, I'm not a fan of "clown puke". Inserts are color matched.
Looks like you have at least one chipped slingshot plastic. I ordered some a while back but color was much darker than they're supposed to be. Ordered another set from pinball centre in Germany since I was ordering a couple other things (the dummy plastic mainly). They don't ship to the US, so right now my stuff is at a friends place in Canada. I'll update on the color and quality when they arrive.
Anyway, enjoy the machine, be sure to post some more pics!
