I made a tool years ago as I work on quite a few LC Smith Shotguns regularly....

Picture is worth a thousand words.....compress the spring with a screw driver vertically, insert the tool, remove the screw driver....

Requires a small notch in the non structural super thin wood internal divider wall, cut a clean notch with a razor blade or side cutters......after assembling the stock and trigger plate, simply remove the tool.....it holds spring pressure off of the lever shaft during assembly for perfect alignment of the lever shaft while inserting the screw without any side load on the threads........

No slipping marks, rubs, gouges or depressions on the wood or metal from clamps or external tools, no force needed to reduce spring tension during assembly etc....

Hope this helps........
