Trying to make my 20 in wheels fit, they don't fit by a couple of mm .... I have gone to several machine shops here in san Antonio , tx to see if they will help me bore my wheels so they'll fit, but with no luck or they just won't want to mess with it or just don't know how to do it... It seems simple to who ever has the right tools, but just can't find that person.. Thanks for the help..
