Thanks guys, I haven't found anyone who makes a larger dog so figured if I wanted one... Quite easy to do and even though I work in a machine shop did it mostly by hand. Traced around the OE dog with a marker and just drew the outline I wanted from there. Next put it in the Bridgeport and plunged a .375 end mill at the base of each point. Band sawed the rough shape out and then worked it up with a file. Basically a drill, hacksaw, and a file is all you need. A good sharp single cut file...and a file card.
Think I'll order some stainless and remake an inner and outer. Haven't run the saw with it yet but I can see right away to lengthen the bottom point another .125 or so to be on the same plane as the bottom of the saw.
