I can get servo boxes that look great out f the junkyards here(key words- look). I replaced mine on the departed 80 TD twice before I got the properly functioning unit. While they are cheap compared to new and rebuilt units, they have only a 30 day warrenty, which means I have to return them and find another suitable unit within 30 days of pulling the unit. PM me if this interests you. Cost is about $100, and that includes finding, pulling, exterior/interior visual checking, packing and domestic shipping.
