ps. was riding around crater lake OR with my new to me bomba this weekend with a friend on his mb-2. I'll post a pic when I'm on my computer. mobile google groups doesn't seem to allow posting images.
Oops...my bad. DT shifter BOSS.
You mean the part welded to the frame?You could use a clamp-on boss just to rig it in a jiffy if you cannot find a better solution as quick as you need.I'd still call Riv and see what they recommend.
