Super Advan SA3R

Hey guys,

Im getting a set of Super Advan SA3R in 16" real soon, unfortunately it does not come with center plate and Nut. After some research correct me if im wrong, found out that the center plate comes in short (COA-12B) and tall (COA-A93-1). But i cant actually find any information on whether the 16" uses short or tall(hoping someone on here would know). Also are the diameters of the center plate all the same, are they interchangeable between 16" 17" 18" etc?

All help appreciated
