I just purchased a 1997 Cat 22. The portside spreader was missing 1of the 2 one inch bolts holding the spreader connector to the mast. I purchased new bolts. The one that was missing has no receiving part in the mast to tighten the bolt to. Does anyone know what is inside the mast this bolt connects to and how to resolve this dilemma? It is amazing the spreader (shrouds, and mast) are all dependent on these 2 bolts. Thank you for your advise.
