Hi, I've never installed a sound board before, so I would really appreciate any help with how to do so. But first, is it possible to swap the sound board in a Lionel legacy tender with a different sound board from another legacy tender? I would like to do this, but if it helps, I have a Lionel legacy mikado, and I'd like to swap the sound board with the Lionel legacy Southern Crescent 4-6-2 pacific sound board. Would this be possible? Thanks.
