L. C. Smith stocks do not interchange. Each one is different enough to have gaps and misfit areas that look like crap when this is tried, assuming you can even locate anything worthwhile, which I doubt. Experience speaking from seeing some of these attempts.

Send what you have to Dennis Earl Smith and see if he can salvage it. He does dome amazing work.
