[quote=Wolfman]Gordonjs, your setup is exactly like my 1981 5.2.
The Jib is supposed to have a single bullet block hanging from the halyard you tie a 3' line to #1 go up through the jib block and back down to cleat at #4. This gives a 2:1 downhaul on the jib.
The main is also supposed to have a single bullet block with a becket hanging from the tack of the mainsail. another 3' line starts at the becket, goes down through #6 back up over the bullet block and back down to cleat #2. This give you only 3:1 purchase on the downhaul, but if you have the original sails and straight spreaders on the diamond wires I would recommend going any higher than 5:1 on the downhaul. The boltrope in the original sails wasn`t made for the super high downhaul loads people are putting in now. Also if the spreaders are straight to the side you won`t get the mast bend needed to make such high downhaul forces effective.
Extra line from the halyards can be rolled up and placed in the tramp bag.
#3 is actually a place for you to lash your halyards to when the sails are down. Almost everyone also ties a length of shockcord to the outside of the dolphinstriker, up through that eyelet and back down to the other side of the dolphinstriker as a jib preventer (keep the jib from hanging up under the mast when you tack).
Replacing the cleats is relatively simple, use part number 27-0702 Aluminum Cam Cleat No Roller - Aluminum (or you can use 27-0236 with a roller) from Murray`s. Drill out the head of the original rivets, pound the leftover rivet body into the mast using a nailset (or nail for that matter), reuse the holes and install using monel rivets Murray`s part number 19-5022 MCP 6-6 3/16" x 3/8". You can use a standard pop rivet gun for this but you will likely need a buddy to help you pop the rivets (the stainless mandrels are a pain to pop) unless you have one of the heavy duty tools. I`ve done about 20 similar rivets using a reguler rivet gun without breaking it.
The mast looks like a pre 1985 so you should use the older manual for advice (everything I have talked about is in there) here`s the link to the one you want: http://www.thebeachcats.com/index.php?module=pictures&g2_itemId=35357
