This FBO distributor,(for RB) and ignition module came with some spare parts with my GTX I used to own. The previous owner swapped it out for a Rev-N-Ator ignition because he wanted the programmable module that came with the Rev-N-Ator. I haven't been able to find any information on this particular kit so I have no idea what they cost new.The number stamped on the distributor looks like FBO 088075 as best I can tell. I don't need it so I would like to sell it. I would appreciate your opinion on what you think a fair price would be to ask for it as I don't want to over/under price it.
