Would like to stick a synthetic stock on it, get rid of the stud that moves with the forearm and use a barrel band sling stud.
If you have the swivel stud that attaches add moves with the forearm, that should be a post 68 gun and they should interchange just fine.
You can usually find the correct OEM capscrew on Fleabay to replace the screw with the swivel stud, that's what I did. I like to shoot the 760's hasty sling style and that damn moving front swivel stud is certainly not conducive to that.
