I've got an OEM plate, depth gauges, assorted shims, & have done lots of boxes. Located in Melbourne, but will not lend tools. If you can get it to my joint, I'll either do it for you or show you how for a BBBB (Big Bastard Bottle of Bundy). PM me for a contact number.
Old age and treachery will always beat youth and enthusiasm, however, there has been an alarming increase in the things I know absolutely nothing about.
