Just take the sway bar out. So it doesn't handle as well on the trail, but that isn't why we ride these sleds. I took mine off last year, and just taped it up, and put all the parts to re-attach it in my pack, in case I didn't like it. Not looking back, taking it completely out this year.
Theres a guy on Snowest that makes one. Its nothing fancy but its a single side QD with a heim joint. Cost me $50ish. If i can find the emails with his name i'll post them here but worth looking in the vendor section.
