Dunno if I can post this here (moderator can remove if necessary), but we used to sell that kit for $150. Again, we don't sell them anymore (we ran out and decided not to do another 1000 piece run). It included the pin, a different aneroid spring, the break off bolt and instructions.
Ask for Dusty or Shawn Arnold if you call Dynojet... I think they are the only two that still know about the kits.
