I had a friend who works in a shop which fabricates Stainless steel milk trailers cut me a couple of scraps of stainless into round circles on the laser cutting table and drill a few holes to match the existing holes a few stainless nuts and bolts some silicon sealant and I was in business. It pays to have friends who can fabricate anything you want from scrap stainless. You should see the traveler bridge he made for me using 1/2 inch solid rod some scrap rounds welded on with a few stainless chain links welded on for connecting the control lines and blocks. Add a traveler from a Catalina 22 (under $40bucks at the catalina parts web site) and you have a great boom end traveler.
