pushrods?
I did this simply because PR lengths typically come in .050 incriments.
I just taped the tool to keep it from turning when I set it at a specific length. There are no markings on the tool you can "dial" a length to so I just measured it with a t square ruler and put a flat edge against the opposite end of the check tool and confirmed that lined up on the measurement marks on the ruler.
very simple. COMP # 7702-1
