Replying to Remounting....

so worst case scenario ill have to get my fks remounted on my new skis. when i adjust the fks the little side arms scrape against my boot. there is some room left to go longer on the arms but the arms just scrape pretty good againts my boot. will they need a remount? i went from a 301mm bsl to a 308mm . also, from a ski point of view, is remounting a big deal? these are my new skis and have been mounted to the fks to the 301mm bsl. so will a remount hurt my skis? they are good quality skis also (kitten factory). any techs out there encounter the scraping on the fks arms? k+ for answers
