Setting up my '82 Mac 25 for the first time. Mast went up easier than expected. Going through the "ok, what's missing" phase. (Personal Note: sailed quite a bit but never put a boat together) Besides the backstay at the top of the mast, there is one cable coming out of the aft side of the mast near the top. I first hooked the shackle on the end to the boom, believing it to be the topping lift. But then, where's the halyard to raise the main? Confused as to which is which and then where is the other. Appreciate any words of wisdom.
