My Prindle 18 was missing sheaves on the 2 block riveted to the mast when I got it. I used it that way for 3 seasons. I just bought and installed two harken micro cheek blocks . They did not match the exact same holes so I put one rivet in the unused hole to fill it. I then used the other hole and drilled a new one to fit. I then bought a small downhaul with a quickpin and two micro blocks on sale at Murrays.
I really wasn't to hard drill out old rivets probably 3/16. Just drill of the head then use a punch to knock the rivet into the mast. This helps to not make the hole any larger or you will have to go to a larger rivet. I bought a long handled rivet tool at harbor freight for $20 and some stainless steel 3/16 rivets from West Marine.
If I remember I'll take some pictures. Seal all the spots you rivet with silicone to keep the mast water tight. I probably oversealed mine I am not an artist with silicone so my mast is not pretty.
