Need ball joint asap

Guys,
I’m in the middle of putting my high clearance arms on and noticed the rubber cup is gone on one of my a arm ball joints. called the dealer and of coarse he doesn’t have them and will take 4 days. He says they are different then every other machine except the 2014 diesel rangers. Can someone help I need to ride this sunday if possible. Does anyone have an aftermarket one crossed over yet.
Thanks
Jody
