I couldn't imagine very many companies make them though. I buy a lot of stuff from classic industries. I never really know what I'm getting though because their description of products and parts included is horrible. However, I haven't gotten any garbage products from them, and my packages always come on time, for that I will continue buying parts from them.
Back when I bought my front end kits Global West only included American made Moog parts in their kits. About the only thing they made where their cheesey polyurethane bushings that they claimed never needed lubrication.
They claimed the carbon impregnated in the plastic would lubricate the bushing. Not the greatest of ideas. I had to take them back apart and drill grease channels and then install Zerk grease fittings to end the squeaking. But after that they were great.
