Recently, I came across a new product that works great to replace cotter  
rings and all those other methods of securing your turnbuckles. It's called a  
scar pin and is available in different sizes. Yankee Clipper has been using them 
 for several months and he is very pleased with the results. Very cheap, but 
very  effective. Photo attached and link to where you can purchase.
