I came across this SG seat on my local CL. I used a similar seat when I did my TP detach set up on my Ultra except I paid $100 for the seat which seems to be the going rate so I igured I would pass this on- I have no relation to the seller but if someone wants it and would like me to pick it up and ship it just inbox me and maybe we can make it work.
