What makes you think you need to replace yours? If it is an oil leak, 999 times out of 1000 its not the rear main seal leaking. It is usually something leaking from the top of the motor into the engine valley and draining out a hole in the rear of the valley making it look like a rear main seal.

This should help POWERSTROKEHELP.COM - The Information Source for Ford Power Stroke Diesel Owners Grab a flash light and start from the top of the engine.

A rear main seal on a 7.3 is very, very rare, I agree most of the time it is a wrong diagnosis by a lazy mech, look up higher for oil in the valley of the engine, or at the base of the turbo.
