Finding parts isn't that bad but you have to be patient. I just rebuilt my cammer, so it can be done. One person you want to get hold of is Jerry Woodland, he is out in Utah (Google him). He carries abut every part you will ever need, he is reasonable on price and very knowledgeable. A lot of cammer owners will add Sprint parts (4 bbl carb, cam, sometimes a new head, etc.) to their base OHC, happens all the time.
