Just did a quick internet search and found this place
http://www.kraftpower.com/products.html This seems to be a very popular industrial engine. Used in all kinds of equipment should be pretty easy to find. I asked one of our techs here who is into the old military stuff. He has a 41 jeep and had a 2 1/2 dodge and an 1/2 track. He says there was a place in anaheim ca that you could get them from but he cant remeber the name. He said that sealed power brand rings had them plus another popular brand that I cant remember at the moment. Damn phones are ringing off the hook.
