They are both made on the same tooling in Taiwan. Tooling cost can be prohibitive for high tooling cost / low volume parts like these so it's pretty common for companies to share the expense.
I consulted on this project, so this is firsthand knowledge.
If you understand the engineering bits that went into the design, then may I ask a question?
If I wanted to get the equivalent of the expensive offset balljoints for more front camber, is there any engineering reason that I cannot just lengthen the A-arm by welding in a 1/2-3/4" spacer to make the cross-member longer?
