Looks like I have 3 1/2 and 3 1/4. If the 3 1/4 will work, I can take care of it for you in a matter of minutes. If not, a 3" bit is probably $15 at True Value or Home Depot. Both of which are a mile or so from my house and we can run over there if you want. I am Between First and Erringer off of Fitzgerald. PM me if you want me to take care of it for you.
