I bought a couple of replacement coin return buttons for my Tempest coin door about 6 months ago from an outfit that I think was in Florida. They work okay Except they are red and not orange. I had to modify my springs a tad because the post on the back of the button wasn't long enough to allow the pring to keep the button pushed out all the way. I also got some coin return flaps and coin entry and return bezels.
I had to modify the bezels to get them to fit, and the coin return flaps aren't even close to the right thing.
I'll try to find the name of the company I got them from. As stated, the coin retun buttons (red instead of orange) are accpetable, the bezels sketchy, and the flaps are garbage.
