Soooooooooo I bought a Bally Atlantis pin cause it was a "deal". There were problems I didn't necessarily understand, and being more of a "casual" pinball collector (if there is such a thing) I am running into some restoration issues I haven't really had to deal with yet.

First off, there are clearly some "hardware" pieces that have been replaced incorrectly. When I say hardware, I mean screws, metal posts, gates, etc... The problem is that I find it difficult to actually figure out the "part number" for a lot of these hardware pieces because the manual doesn't have them. For instance, there are 4 metal posts that sit on either side of where the game pops the ball into the wireform vertically. One of them is NOT correct (at least 1). How can I find the exact post I need on Marco for this? I posted a picture for it below.

Secondly, I got a plastic set for the game, but I realized after the fact that there are these built-in metal spacers on the slingshot/inlane plastics that I don't necessarily know how to remove or apply. Any help in figuring that one out would be appreciated. I did find a Marco part for the spacer, but it appears to be out of stock . Hopefully I can reuse the old ones...? https://www.marcospecialties.com/pinball-parts/20-8926 . I also attached a picture to show them in place.

Thirdly... I don't know why I can't find this one... it's a little embarrassing to be honest, but what bumper caps are these???? I must be missing the part number, but I didn't see it on several searches. Are these crazy special pop bumper caps???

Thanks for the suggestion Yves, I believe you're referring to this topic:
https://pinside.com/pinball/forum/topic/the-bally-atlantis-that-i-discovered

Unfortunately it doesn't really answer any of my questions above specifically. Also, I was kind of hoping someone would be like "OOOOOOH, yeah I didn't know this either... all you have to do to find the specific screws/metal posts/etc on a game is go to <insert secret formula here>."

I did search through that particular restoration with no luck . Is there another one you were referring to?

Yeah, I always read these topics on restorations and they sort of gloss over a lot of these replacement parts. I was hoping I was just missing something really really obvious.

WOW! Why didn't they make a parts manual like this for all pinball machines?!?!?!

Unfortunately, I don't think the specific parts I'm looking for are there

Yeah, I actually do have 2 of the "pushdown washers" for the two top posts, I kind of figured I was missing 2 for the bottom posts, but possibly you're telling me there's only 2???

And yeah, I am desperately trying to find the correct post with the rubber grove in it, but I don't think it exists in Marco. I've searched all variations of "post" and come up empty. I'm kind of wondering if I could get away with using a double grooved post because they have those. Maybe I could just buy 4 and put an extra rubber on just cause it doesn't really matter.

This is the closest thing I could find (with double grooves):

I'm also still trying to track down these bumper caps. Mainly to figure out what screws go in them, because I'm missing a screw on one.

Awesome! That solves the mystery of the pop bumper caps, and collars but unfortunately the screw is still somewhat of a mystery. I was hoping it would pop up under "related items". I actually have a few spares of the one you mentioned above. They are, however, too short. The screws are a bit longer than that. I'll just take it over to the hardware store and see if there are any matches.
