Its seems to me that I can find out more on CDC than I can on any other website. I know about Cooks in Clinton, MO. But I figured I would ask if anyone else knew of another place that I could get good quaility used tractor parts. What I am needing is a exhaust & intake manifold for a 806 IH Farmall tractor. Its of course a gas tractor with a 301 inline 6. Would perfer to get the manifolds off of a combine due to the fact that they wouldn't be as used as ones off of another tractor. And I would like to save some money if I can. I have found the exhaust manifold online for around $240.00 ouch!
