I bought a set of these Manley I-beam rods from Mike Bogina. He had them on the shelf. I had them checked by my machinist and the rod bolts had some galling on them from the factory, so we had to replace the rod bolts, dowels and resize the big ends to fix the problems from Manley. I'd only buy rods new from the factories after that so I can return them if they aren't right. I don't know if Manley still makes these or not.
