don't know what your talkin bout mat..?
washers? maybe spacers.... but not guides, like mine anyway.
i'm gonna try to go to hallet, watch, work, or play. haven't decided if i will take one of the cars. 3 mos. into retirement and getting things finally finished around here, somewhat.
NOTE: yours is the different belt, and they might argue that is the reason, but i would still use guides. especially in lieu of not being able to adjust the belt. if they insist in not needing guides send them a pic and get in writing they will guarantee their belt not to jump
