You might want to add or sub in 4 or 6 of the 7/16 Outside Diameter size instead of the 3/8 OD for some of the steel pointy posts where you'd want more thickness - like by the pops. Slings are 2.5" (left) and 2" (right) if you want to get extras.

I needed a few rings in addition to what is listed here.
1x 5/16 ID to the left of Whiplash
3x 3/8 OD for posts (I actually used 7/16 instead)

I ordered this kit and can not for the life of me figure out where the 1/2 Inch Post Sleeves should go. Also this kit does't include a plunger tip so I missed that in my order.

After installing I can confirm that the 1/2 Inch Post Sleeves listed in this kit are NOT needed. There are four standard black post sleeves in the game and they don't need changed out in my opinion. There are a few other issues with this kit as listed. When replacing the ring by the roll overs I noticed that the stock rubber was larger for the top ring than the bottom. This kit has you replacing them all with the same size ring. Not a huge issue and the game seems to play fine, perhaps even a little faster getting the ball down through the roll overs now. I had one ring left over for some reason, I think it was the 1 inch ID but I'd have to go back and check. There were two or three stock rings under the back of the right ramp that I couldn't get to for conversion. That would have required removing the right ramp completely and I'm still not sure how to accomplish that. I added Pinbits plastic protectors while I switched out the rings and they look great. The entire job took about four and a half ho
