I never got around to installing the Powerflex yellow polyurethane insert into my P3 torque engine mount and the car was totaled recently so I have no need for this. Insert was never used and is brand new; opened to verify that the insert and grease packet are intact. $28 shipped.
Eventually going to get a another P3, but may end up with something on the SPA platform so I won't be needing this unfortunately. PM if interested. Thanks!
