S281 Spoiler Installed...Another one!

Hi. Just saw your post about your new wing and Was interested in seeking information about a SR 351 Spoller I just bought and had painted. I thought this new wing would mount through the existing holes from the original spoller but it will not. Do you have any suggestions on how to get by this problem? Do I have to cover up the old holes and make new ones or how do I get around this issue? Thanks for your help.
