Tom, here is a link to the thread I started for the tri-glide install. //heartlandowners.org/showthread.php/10622-Trail-Air-Tri-Glide-Retro/page4?highlight=tri+glide
If you decide to do it or have it done, have your installer clean up and repaint the entire pin. It looks much better than the factory job. I'm pretty sure they don't use primer. It would be great if they were powder coated.
