Thanks Bill. That is is the same Jib box I have. Rig-rite is now selling part K-11597-1 as a replacement, which they claim is much lighter. Do you have any idea how much yours weights?
With the existing sheaves being riveted in, you can drill the rivets out and replace them with cleaves pins.
Looks like we're pretty much stuck with rig-rite for the replacement sheaves. The sheaves are 31/64" wide, and 1/2" looks to be too fat to fit. I'm probably going to get the Nylatron replacements for the spinnaker and jib halyards.
I had a crazy idea to try and replace it with the stick up, but I've been told this is a bad idea, so I'm going wait until this summer, and do it when I drop the mast to inspect it.
