i looked at the brothers site tech section, it looks like a pretty easy swap to me. i still don"t quite understand the rod alignment problem several posters have mentioned. how does the rod not align properly ? is it too far toward the outside of the truck or to the inside? or is it not aligned up and down? or is it not aligned front to back? thanks for all the responses and keep them coming. after seeing the tech article on the brothers page i am especially interested in people who have used their system.
