I sell the Dorman regulator and they are good quality, just as good as the GM part. None of the sets come with the mounting hardware and you can usually get away with nuts and bolts so long as you use a locking nut or other type device to prevent them from backing out. the POP rivits are the best but the giant rivit gun is not practical for most of us to own.
