I believe that water pump pulley is 9788886 XT. These alone go for $25. I think that there is a chance to get $100 for that set. It all depends on who's attention you get. I see people wanting these at least 10 times a year just on this board. It would be a good auction. Better in the fall/winter when more people are looking for parts. Set your reserve at $49. You can easily sell them for $50 here if you be patient.
