Hope this is the right place to ask this question...just bought a scope for my old Winchester 100. Bought on-line and got the 1" O-ring clamps for the scope, but they did not have the base plates to mount on the factory drilled holes of my model so I got the closest plates that they had thinking I could simply redrill the holes in the plates if they did not fit. (No need to mention I'am a newbie at this is there!) Anyway the scope is popping a wheelie. One base plate is thicker than the other. (Did not have to tell this whole story either, but I felt so stupid I felt I should post it so you all could laugh at me ) Is there a site that has plates for old guns, or a site that might have plates for my old Win?
