I have a 1988 profurl P40 on my 34 Catalina. ON the drum part there are 4 guides that stick up and retain the line around the drum and they used to have little rollers on them. These look like long skinny thimbles (like thread comes on) and slide over the guides that are 5/16 in diameter. Now my question is where can I get replacement rollers? I emailed Profurl twice and got no answer. I emailed Maui sailing gear who handles profurl and was directed to contact profurl direct. So ?? anyone know?
