Quoted from cmack750:I've had good luck buying kits using the ring kit database from Titan. Doesn't include a ring chart, but I've found most of the kits I've bought from them to be pretty accurate.
I'm considering getting white silicone from Titan for #Heat Wave. They don't have a kit for it. The Williams Parts Manual at Planetary Pinball doesn't have a ring chart.
How do I correctly measure to get the right size? If you simply measure the distance around the posts, the ring wouldn't be tight enough. There's got to be a 'rule of thumb'... ?
