Hello mudboger07,

Taking off the CA hinges easy and fast,....all you need is an exacto knife and just slice the ca hinges off. Now you can use the same exacto knife to very,...very,..very,....patiently cut out the rest of the left over hinges inside the tail. This is a very slow hof and requires a lot of patience....Or,..if you can just leave them in there and put your robart hinges just under or over where the CA hinges were,..this way you don't have to go through the long trouble of taking the left over hinges out. In the past I have left the left over hinges in and placed the reobart hinges just over or under the old ca hinges and it has worked fine for me. Good luck,...
