Got my line ran though the boom and all is in order. For anyone in the future who may need to do the same and finds this on a search:
The aft line of the two needed to be run though the block in the boom. The block was all the way forward as that line pulled it all the to the mast
. I snaked a soild wire though the boom from the mast end. This wasn't as easy as it sounds as thw ir would get all bent up and get stuck. I finally put a loop in it and got it to about 3' of the crew end where I was able to use another piece of wire and hook it pull it though the end of ther boom. I then tried a 3/16" nylon line to it and pulled the line back to the mast. Loosed all the lines and lifed out the pulleys for all the lines (the outhaul
and the 2 reef lines). after many attempts threaded the nylon line though the block and tried it off. Untried the reef line in question as loose as possible (but lined off so it could pull off the block making me stat all over on the forwrd end of the block).Pulled the line/block back aft and after a few "back and forth" worked the block though the opening at the end of the boom. Then it was just amatter of threading the reef line back thougfh the block and putting everything back together. Was getting a little worried about getting the pulleys back in the mast for the lines but just had to keep working on getting them aligned to go back into the slots.
So in the end it was possible to run the lines without having to remove the end cap from the boom.
