I need the sheave size for the masthead. I measured them once, but can't find the info. I know I sent it to mcollins, but deleted the "sent" file. Anyone know the width? If I remember, the diameter is 2 1/2 inches.

Tom, here are the spec's you sent me. the mast sheaves are 2.5" x 9/16. The 9/16 is exact, which means you might have to shave off a 9/16 sheave if it doesn't fit. Michael Collins
