OK, I stumbled upon a .pdf file I had downloaded from this site, which I have attached, called Contact Information. I emailed the fellow identified on that list as being the Rockwood parts contact. He emailed me back stating that he no longer had that position and gave me the name of his replacement. I emailed her and got an auto reply that this person was no longer employed by FR. This emailed stated my email had had been forwarded to Ruby Gonzalez, RGonzalez@forestriverinc.com
. I contacted Ruby who replied she was the Flagstaff parts contact and that a new person was being trained for Rockwoods parts, but that in the interim she could assist me. Long story short, the part is a right hand black radius cap, part number 10-15093a, $3.86. A call to Ruby with shipping info and CC gets the part on the way to me.
