I used the HAIR PIN on mine. The front of seat should have been a little lower but I ran the wiring thru the frame and didn't want to burn it up.
It ride a LITTLE low for me in the back so I will be adding a back to the seat for crusing comfort on LONG trips.

It ride REALLY nice. Before I put the springs on the seat, my chop would BOTTOM OUT on the BAD CALIFORNIA road. Now I don't hardley feel the bumps at all.
