Here are some photos of how the brackets mount (seat tracks are currently disassembled for cleaning/painting/lubing). These brackets relocate the seat almost 3 full inches back. All hardware should be Grade-5 or better.

The seat tracks in this photo are upside down to show how the brackets are attached. The rear brackets are attached to the seat tracks, the front brackets are attached to the seat frame; all using the same mounting holes for the tracks to the seat frame.


The next two photos show the rear of the tracks in position on the seat frame. The same track-to-frame bolt (5/16-18x3/4" bolt not shown) is used to attach the bracket to the seat frame.



The next two photos show the front of the tracks in position on the seat frame. Use 5/16-18x3/4" bolts with nuts/lock washers to attach the seat track to the front bracket (mounting hardware not shown).
