I ended up buying the wrong size from ebay
They were very cheap but I do not want to wait a few weeks to order more. I need a 2-1/2" size. I only need it for three holes. If you want, I can give you one of the ones I bought...maybe the 50mm. Never been used. Otherwise, I can compensate you for your troubles.
If anyone can help out, that would be awesome. Or if anyone knows where I can buy one in vancouver for relatively cheap that would be great!
