Chris, my SS is parked next to my Scout II, so here is the comparison. The SS sun visor clips are rectangular (1.25" long and .5 " wide), tan colored, plastic and mount differently than the SII. The SS clips have a .5" wide U channel on one end that latches the sun visor but the channel opening points toward the front seats and the mounting hole is at the other end of the clip. The SII metal clip's U channel opening is toward the windshield and its mounting screw is located in the channel itself. I think the alignment pins are different in both places too - meaning you cannot use SII clips on an SS. Hopefully Paul and some of the others will post a picture - I am camera challenged at the present. I am now wondering if these clips were used on other IH vehicles (T'All, Pickups, etc) that might be another source.
