Thank you Nate, but I have that rpl (L&R)lock in my shop and the problem is reach, if you use the same peg positioning hole in the lock plate, then the end of spring cannot reach the tumbler. It would work only if I relocated that peg hole rearward about .200 or so and re cut that little notch on the underside of the bolster to catch the spring top. An actual cva spring may fit but I dont have one, and they seem to go bad easily and weaken.
I just thought maybe,.. Someone here may have one from a Russ Hamm.
