Has anyone heard of “Crauler” B4 insert bearing con rods . I bought some at Hershey and that was the name the vendor gave for the insert bearing rods which he had written on the box , which to me the very uninitiated , look a little like Crower rods. But a fraction of the price. Well they had been run but it wasn’t obvious looking at the bearings. This is the only crumby picture I have as buddy has them in his pickup on the way to our international shipping.
