These are similar to the Mark Hodge bars which I have. They work slick. Mark Hodge's have little chains attached to the clevis pins so you don't lose them, and his clevis pins are the type with the spring-loaded ball on the end rather than having to use cotter pins--a slightly more convenient set-up. Cost for Messick's is about the same, and in my opinion well worth it, and they look to be readily available. I had to wait about three months for my MH bars.
