Here is a pic of the bracket and seat mounted on the bike. I still have to parkerize it.

Here is the front mount, This goes in the seat post hole, The pivot is a vl shift quadrant, and the bushing is from a 39 to 65 shift pivot.

Here is the finished piece.

Here it is welded onto the bracket. The bracket is an o.g. buddy seat bracket that I twisted and cut up.

Here is one of the bungs that the seat springs sit on. I cut a groove in them, so that they slip over the bracket that bolts through the top fender mounting holes.
