Question Asus WS Z390 Pro Thunderbolt Header

[Yogi2367]

I have a Asus WS Z390 Pro motherboard and it has a 5-Pin Thunderbolt header on it. Does anyone have any idea where I might find a Thunderbolt slot header and cable?
Could not find one on either Newegg or Amazon, and Asus is not much help ... 3 different support techs, over 3 messages, in 24 hours.
