Hmmm, spacers? I have a third central platform from the Tarot, and if you try to mount it, then the aluminum spacers need to be attached to different holes. There are many, but the diameter of the holes are smaller than the ones originally attached to the spacers. Therefore the bolts which have a collar go in but the collar doesn't. However if you use the "spacers" then they seem to be just perfect for the bolts to fit in the other holes. Could it be that?
I sent the question to Tarot, hopefully they will reply.
