Ok, this is the way we do it. 1. Butt both ends. 2. The lifters are Bob's, the only good ones. Take all the bolts out, and nuts off, and either blast, or wire brush the threads. Make sure the nuts do not move the bolt when installed, that is, rotating freely, and assemble bolts. 3. Put a heavy greas...

Ok so how do you keep the lifter from turning when you snug down the lock nut without using 3 wrenches?
