Here is another reference....
Mark referred me to Deer Creek Products (765-525-6181) which he said had purchased much of CVA's stock of parts. Why Mr. Meredith didn't give me this information when I asked him (via Email) where I could obtain a barrel rib, I'll never know. I ordered the parts in question from Deer Creek Products on Monday, February 25 -- a week after I'd initiated communications on this with CVA.
