Thanks for the great info. As I looked again, you are right. I should be able to cut out the inner web, install the outer and then place a new inner web on. That isn't much work so I'll go the safe route and add it.

Thanks for the advise on the CA hinges. I had heard that those represented a good technology. You scared me about the "bad batch." Are the Robarts easy to install? I have only installed the CA hinges before. Maybe I should just buy some Sig CA Hinge material at the LHS.
