Quoted from wdennie:I get rid of the cheap looking plastic acorn nuts, and add 2 washers one on top and one under plastic, and chrome arcon nuts, looks so much better!
Quoted from BertoDRINK1:Probably not the most favorable option but i just don't like the look of them.
Disagree. Comet gets white nylon acorn nuts...at least, that's what is on the flyer. They look great when you replace them with brand new. Add PETG clear fender washers under the plastics.
Quoted from zacaj:Confused, why the washers?
"Crystal clear protective washers are made of PETG plastic, a nearly undestructible high impact type of plastic, much more durable than acrylic
Clear polycarbonate fender washer for protection of slingshot posts and other high ball impact areas"
Quoted from zacaj:I understand the large clear ones. Wondering about the small metal ones.
Probably shouldn't be there - perhaps someone added them.
The OPs game is Supersonic, so the correct cap to use should be these white rubber post caps

Those are rubber post caps in the flyer pic.
Here is another link to a discussion thread. I am in the belief that the flyers *possibly* do not always match production games, and both were used around the years of this Bally era. My 1981 Bally Elektra had the rubber caps...and regardless of keeping a game original, eventually you end up finding these critters down in your outhole

Quoted from Pinball_Nate:So plastic are *supposed* to have some play in them? This helps them absorb impact better without breaking - hmmm, makes sense, although I could see some rubbing on the underside of the plastic as a result unless you put some mylar down on it.
That's where the plastic washers or full plastic protectors could be a solution. I've always thought the protectors or washers would go under the plastics, because that is where the art is printed. This is just my opinion, as I generally keep my games original and don't go out of my way to add all these extras.
Quoted from Pinball_Nate:Yes, they would.
I actually made my own protectors for the infamous center plastic in Taxi out of heavy plastic, and it seems to be doing the job. May do this for my Meteor project also.
On my ex-Taxi after that plastic broke a 2nd time, I just left the cracked center plastic in place and installed the replacement on top of it. That one sure takes a beating!
Quoted from tomdrum:I have to respectably disagree. I have bought 2 dozen early SS Bally project games, many in the early 2000's which were from operators warehouses that still had the OE #44 brass base bulbs under the plastics and PF. Supersonic was a March 1979 release. While I've haven't owned one, I have bought a Star Trek 4-79 release, 3 Paragon's 6-79 release, 4 Silverball Mania's 2-80 release and a Space Invaders from 4-80. All had the nylon post caps. 1st game that I encountered that had rubber post caps was Xenon (11-1980). I know I'm splitting hairs but I believe the nylon post caps were installed into 1980.
hmmmm. you left out 1979 Future Spa and 1979 Dolly Parton

A lot of KISS had the rubber caps, but you'll see the nylon caps on a lot of them as well. It also looks like nylon caps on the flyer. I'm going to go with 1979 as a transitional year. I don't think you'll see many, or any 1978 and earlier with the rubber posts factory. Anyway, it's really not all that important. We can always install what we like .
