Retread -
Gabriel has a section in their catalog which shows every shock they make from the Red Ryder line, Classic shock line, Fleetline, etc. which shows expanded length, compressed length and type of mount they fit. Each section starts from the shortest shock to the longest shock expanded and compressed. Granted there are not that many choices, but you need to see them all to see which will work.
You need the PRINTED catalog to do this comparision - not their computer. Ask them to see the printed catalog and if they don't have one, call the distrubtor or supply warehouse.
Good luck!
Joe
