well i've had this thing for several years and i think its time to let it move on. im including both of my custom made(by me) tops and a brass mount for 775/1366 as well as a backplate and 2 sets of mounting screws. you will also get the stock top as well as the dtek nozzle kit which works in my tops as well. so this block will work on am2/am3/940/939/754/1207 and 775/771/603/604/1156/1366 with the included hardware. the base as been lapped down to 3000grit. everything is mint. this block was used mostly for designing my tops. its only seen water a few times for testing only. asking $55 pending i will consider trades but im picky. just offer though.
