Pete, Are you sure about those part numbers? My '72 Pantera L came with red painted single-adjustable #82-1701-SP front shocks and 82-1601-SP rear shocks, back in 1980. To differentiate the fronts & rears, the rears had heavier springs in back, and the bump-rubbers in the rear had a longer taper on the end. The front bump rubbers were more flat. Can't check 'cause I sold them a decade or two ago.
