Had to put in an order with March a couple hours ago...
While waiting, I remembered this thread.
Anyhow, the MCH-1176 is the old one.....the MCH-1158 and the MCH-1176 are the same part....just changed part #'s. MCH-1158 is the old MCH-1176....
Still not for a Mach 1. Could it be used on a Mach 1? I am going to use mine on the Mach engine that is about to go in my car. I am a firm believer in them.
