The rack and seat was the only thing heavily modified on the bike. To get the saddle as low and flat as possible I had to reposition the rack lower and create a bolt-in hidden mount to take the place of the seat post.
The other modifications to the rack included attaching the would be curved fender braces to it and cosmetically changing the stamped grooves in the top to end behind the saddle. It also had to be narrowed at the front for the saddle to sit flush.
The NOS Troxel saddle was recovered in leather and 'aged' along with the painted fiberglass to look worn in.
