175 bucks seems steep, especially thinking that the only benefit would be switching to an A/N fitting, which unless your going real racecar, the benefits are negligible. If it also solved the issues that aftermarket fittings present (no control valve), I could maybe understand the appeal for a part like that at such a cost. Lipstick on a pig is the common M/O for the S Chassis...but I guess to each his own.
