Matty, you seem to be a Keeper Of Odd Knowledge (KOOK). Is there a "key" to the number/letter code OMC used for the Cobra Drives? For instance my rig is a 302APRAMH. And I know there are a bunch more codes. I have a 602 page factory manual which I will gladly donate to your efforts but would like to know what year(s) it covers.
