I know this is a pretty dumb question but what is the correct slingshot rubber size for a 80's/90's Bally/Williams era game? I had always thought it was 2-1/2" but while recently looking to get a set for Funhouse several vendors (Titan, PinballCenter, etc) don't include sizes any bigger than 2" in their game-specific kits? Is this correct and/or was Funhouse different than other B/W games?

Thanks for the replies everyone. Manuals are notorious for listing incorrect parts and sizes - rubbers in particular - so that's why I posted the question on here. I was looking to get a sense of what people actually used.

Jeffc - that sizing chart is handy. Thanks for that!
