Yes they did. QA1 bought up all of CAP’s designs and took over all production. I don’t think they inherited any of CAP’s liability or service on previously made parts. Some of the designs were changed significantly, like the UCA’s which don’t look anything like what CAP was making. The K frame looks similar but had a few key redesigns. The lower control arms were basically unchanged initially, and the adjustable strut rods were not changed at all (nor did they need to be).
Perhaps
@QA1_Steve can comment further about the details, since I know you have a bunch of CAP made parts
