There are two kits, one for long bed trucks (2wd or 4wd, QC or RC), another for QC SB trucks (2wd or 4wd). There is enough room on the frame to move the mounts up or down (or flip them if you need that much height) to work with all of them. The instructions have you use an angle finder so that they are setup properly. I can't post prices here on the forums consistent with the guidelines. If you call Enterprise and ask for Doug he'll let you know prices and put you on the list.
