I designed this to fix an issue with rear steering being out of alignment. They are a bit fat for this use, but should be sturdy. Fits suspension link balls (albeit a little too tight), so could have other uses as well. Attach to each other with m2 hardware. I just nipped the head of an m2 screw.

Link balls were purchased from moforc - https://www.moforc.com/products/scx24-brass-link-balls-x20-o-rings-x40-use-them-for-whatever

Please post a make, comment, something. I'm sooo bored.
