1976-89 A/B/F/M/J/R proportioning valve

wanted: non wagon/HD proportioning valve in good working order from a '76-89 A/B/F/M/J/R like the pictures from my '76 FSM with 117 PSI hold off/300PSI split point. verified in my '85 M body FSM that the standard duty valves have the same hold off/split point. PM me if you have one and how much. bonus if you're in West Michigan.

Thanks
