Cracking at the mounting holes was a common problem on the earlier front mudguards, especially if unshouldered fixing bolts are overtightened crushing the part. A fix is to make some sandwich plates to span between the two fixings on each fork leg and glue these in place.

The mudguard design was changed (‘96ish?) to thicken the plastic at the mount. The mount is more wedge shaped, giving a smoother joint with the fork leg.

The next change was 2000ish when the brake calliper fixing bolts increased their centres and the mudguard mounting became two pairs of nylon bands. Those have different fixing centres from the earlier ones, though can be fitted if you make pairs of plates with three holes in each: one to bolt to just the fork leg, one to just the mudguard, and one to both the mudguard and the fork leg.
