    Floor Base Repair Kit

    The kit arrived in great shape. Unfortunately I ordered the wrong floor base. I have sent an email to the supplier to request a return and reorder.

    Perfect! I have been looking for this for several years and trying to improvise a replacement bushing for the base. This fits perfectly.
