I can't help you with parts specific to your M2, but in the Durant hierarchy that is a popular model so someone should have parts. Things like tires or other consumables should be an internet search away. Mac's Model A and T parts, might have some interchangeable parts. Olson's gaskets in WA state, Coker tire for tires(don't buy tires until you're near the end of your restoration), and the index at the side of this page will show you some part suppliers. Try doing all this before the internet! It was Hemming's Motor News, swap meets and junkyards,(which are all still places to go to). But in my day sonny.....
