Gen 2 Coyote exhaust phaser bolts

[stangmach104]

Hi guys. I have a gen 2 coyote crate engine and I did a cam swap on it and bought all arp fasteners for everything. I ran into a problem though with the exhaust phaser bolts being left hand thread. Does anyone know the ford part number for the replacements as they are TTY and cannot be reused? I tried 3 dealerships, fordparts.com and ford performance and so far nobody can come up with anything. Thanks for any help.
