Yeah, time for a rebuild or replacement. If it's minor it's probably more of an annoyance than a safety issue, but knowing you are building this car to carve some corners, it certainly won't help that.

ProForged is about the best stuff out there right now. Taiwan made vs some of the cheaper Chinese made stuff. Even much of the Moog catalog is off-shore these days. If you have a local shop with the ability to actually rebuild the center link with quality ball joints, that is likely best. It'll cost the most though.

Also check your rag joint. There's a good chance this is also contributing to your steering slop.

And yes all of these replacement parts will work with the aftermarket suspension components that are designed around the factory frame. Even the ATS spindle if you end up going that direction.
