Any interest in making these at Ballistic?
Goferit is the only option at this time and this could be a decent market to tape into...

Whats a Dana 30? :flipoff2:

I haven't hit puberty yet... I don't know how to use a D60

I was looking for the exact same product - I ran the Goferit product years ago on my old 30. Recently I was looking for the same thing but for a 1-ton TRE - found 'em by Teraflex. I got the large ($13) but they also have a small ($9) which might be what you are looking for...

Hey thanks for those! I do perfer the solid Goferit ones but this is another option!
