5.2 - what rings?

Hey Guys, I've got a '96 5.2 that I'm getting ready to build. The machine shop only had to hone the bores, so I'm using my OE pistons.

I've read on numerous threads that the Magnums used metric rings. I've noticed when searching for rings nearly all results are for 5/64th top and second rings which I'm assuming are for the non-Magnum LA's.

I measured all of the rings that came out of my pistons, and they're all .078" which is 5/64"... If they were 1.5mm, shouldn't they measure .059"?

Is there a std size moly faced ring PN you guys can recommend?

Thanks!
