So I had found a site for a parts supplier for many of the pacesetter and commuter trikes a while back and thought I had posted it, but after looking around myself I could not find the link. So here it is again.

Unfortunately, I am still looking to find fenders. Ron Kimball over at http://www.powertecparts.com/ said he is looking to get some front fenders
made that are the same shape. Powertec supposedly bought commuter back in the day, so hopefully something will come of it.

I may have a company reproduce the fenders, but only time will tell.
