I have a Mr Gasket one I got from Summit about a year and a half ago. I don't remember the PN. It took months to actually receive it. Good thing I was in no hurry for it. I already had a timing set in my parts pile or otherwise I would have just bought a multi-keyway set instead. I believe the MG key is 4 CAM degrees; i.e. 8 CRANK degrees. I degreed the cam twice with the offset key to make sure I hadn't screwed up and came up with approx 8 degrees more than the straight key both times.
