Keeton seed firmers for John Deere planter

Have 16 New in the bag Keeton seed tube mounted seed firmers to fit John Deere XP Pro row units. May fit others as well. Keeton part number 100101. Shoup part number P100. These do not have tubes for fertilizer. I ordered them a year ago to put on my 1770NT planter and then I ended up changing to a different style seed tube and these do not work on that style. Everything needed for installation is in the bag for each one. $400 or best offer for all to go. Located by Marion ND. Text or call Seven01-Three20-Five609 for info.
