I would like to point out that the link "bosspics" which Brad just linked shows a boss machine with the upright section, possibility, mounted backwards. At least it is not the same as mine. The upright stand, which is mounted to the seat has the head out in front and the latches are on the left side(sitting on the machine). I wonder if someone had the ratchet/angle bolt out and reinstalled the whole unit backward? It should still work and may be the last person to use it was left handed?
