Miles,
Thanks to you and your info, and this great forum, I went to Prevost Mira Loma with your part # in hand. I asked for the parts including the 4 clips and they had it all. I mentioned the problems if this fails and Mr. Prevost parts called Bill Jensen. I walked out the door with all the goods and no bill!
Again, what a great deal and there are some that complain about the 100 bucks! I can now renew my POG membership for the next 4 years.
