I have been looking at making a set using these rebuildable units.

Looking at making some CNC billet front and rear lower control arms for my CR at some point.
I've had requests for arms in the past but they are a fair bit of work to make in 4130 tube. One of my concerns about making them for others and why I have refused is engineering compliance. While I'm confident in my own welding and design I'd worry about supplying the parts to someone else. There are a lot of variables. Once a CNC program is written however it should be straightforward to make consistent accurate arms that I can get an engineer to sign off.
Cheers
