I have a 97 and am in Boulder. Arrived here 6 months ago and the old lady didn’t like climbing the canyon Nederland everyday so got a commuter. Latterly I have been kicking the idea around of selling. Mostly built but she needs a few things now, which I would do myself but winter is kind of...
If you are looking for the middle 4 pintle hitch bolts, they are M12 x 1.25 x 50. You will only need 2 nuts (nylock type as mentioned in the above reply) as the top two thread into the frame cross member.
I went to replace the gears/caps in my driver seat but apparently the PO removed the part that attaches the gear on each track (see attached photo). I guess this was why only one side was moving when I tried power it back/forth. If anyone can help me out, please PM me. TIA.
