Here's another grandpa's opinion- - - - -Palnuts for stovebolt connecting rods are usually available on ebay if you've just gotta have a full set, but they're about as worthless as windshield wipers on a duck's butt! They won't keep a loose connecting rod nut from backing off, and a properly torqued one one stays that way because of the stretch in the bolt, not any sort of external locking device. Other engines such as International truck used cotter pins to secure the rod nuts, and I've seen the pins get loose, wear out, and end up in pieces in the oil pan if they weren't locked into place correctly when the engine was assembled. Nothing beats proper torque for keeping bolts and nuts tight, not even Loctite!
