RE: COX Part
Forget Andersons! Not all of Anderson's is low, some of it is very overpriced. Still a great read, and much better than no guide at all. Cox stuff is hot, as it should be.
A complete and nice RR1 is worth $200 plus. Worth it, one of the most rare and interesting Cox engines.
So, you got an RR1 with a bad tank? Maybe it's worth more in parts? Or maybe you can have it re-anodized.
