Cylinder Head Stud Sources

I am rebuilding a Z129 engine from a TO-30, and I am having a hard time locating Cylinder head studs, and an oil pan drain plug. It seems these would be easy parts to find, but I’ve searched Yesterday’s Tractors, Steiner, SSB, Walt’s, and several others with no luck. Any help you can give would be much appreciated. Thanks in advance. June 26, 2014.

I will have to do some checking but these drain plugs have become hard to find. I will do a dealer search and see if I can locate one for you. As for the studs, there are two different lengths used, 1 7/8″ which is part number 353964X1 and 4 11/16″ which is part number 1035877m1. Both of these are still available from AGCO Massey Ferguson.
