At this point I'm lost, I've ordered just about everything that should work and everything I've received doesn't! I'm at wits end on how to replace the elusive pulley to pull up my mainsail. I ordered a cheekblock for the main halyard; I've asked for a sheave that pulls up the mainsail; I've sent a drawing of what I took off, and still it doesn't look like or do the what was there or have the mounting to do the job. It appears the boat I bought didn't have the original pulley for the main and the one I used last summer was the block for pulling the jib. I don't know what to do at this time and the clock is ticking for bringing the boat to the marina for the summer. Is there anyone out there who has had similar problems on rebuilding a Mac' mast? Mine is a '83 25'ft. and all I want to do is find the right pulley, block, sheave, or whatever the appropriate name is to pull my mainsail up. Can anyone out there give me some direction? (I've tried the parts sites without much help.) Thanks and sorry if this is one of those redundant questions. Rich
