You can get on Newark website and hunt some down I am sure. Pretty good site, with specs, drawings etc. You can take the part numbers and find small packs instead of bulk etc. Learn to work the filters on the search and it gets much easier.
I saw some of these somewhere while searching for some kits of bullet connectors, for boats etc. May have been on Amazon since that is where I got the kits I needed? Remember it said specifically FORD.
