FOLLOW UP... I ordered the 22mm size from TP Republic for my 45mm PO. IT was actually like 21mm and had noticable gaps... They said they'd replacw when new shipment comes in.
Haven't seen replacement yet, will follow up. In the mean time I found this...

SUPER REASONABLE price, just arrived yesterday with install tool, and 2 sets of spring pins... Impressed... It looks just like OEM.
