Hmmm... Also see where the stanchions fit into the crown? On the bike pic it looks like the bolts are at the rear. In the catalogue the bolts seem to be in the front.
I may be wrong though.
Marzochi from that period are great fork. I used to race a xc500 on a kona AA back in 95. I loved it. Except it a little flexi, like most of the other fork of this ages.
