duralast ball joints vs moog

I'm not sure if this company makes ball joints for vintage stuff but XRF Chassis has by far the most superior ball joint on the market today. They are Canadian made. Far more tensile strength than Moog. I used them on a customer's suburban that hauls horse trailers over 140k miles ago and they are still tight. They are worth the extra dough. Oh and by the way the owner of XRF was an original engineer of Spicer.
