so i bit the bullet and bought them from a KIA dealer. good news is they are exactly as described. A firm, nylon bushing to replace the softer rubbery (poly?) bushing at the base of the shift lever. Fits other Mazdas (323, 626, GLC, MX-3, MX-6, Protege 5) and Fords.
also good news, because you have to destroy the rivet if you plan on replacing the bushings in the pivot fork, there is a KIA part number for that too!

these correspond to their respective Mazda part numbers and will save you $3-4 for having a KIA sticker on the bag instead of a Mazda sticker. if not, it'll save you an extra trip. hope this helps.
