Finding only scarce resources and references, I finally the TankoGrad book that covers these. It took me a little while to decide how I was going to do this, but ended up ditching the M60A1 for an M577 to do this in because of the flat surfaces and better references.
I ended up using graph paper that I lines with some adhesive foil on one side for durability and then used a tiny pair of scissors to cut out masks that were scaled to the four inch squares used on the vehicles.
I'd love to see other's that have done this and how they ended up doing something like the M60A1, but I think the M60's were just painted with a paint roller and didn't follow the MERCD scheme the way they did on the M113 series.
