I'm having to order a few parts for a 1935 King bass. One part I need is a new tailpiece and tailpiece wire. Is there a correct size I need? The original tailpiece is cracked, and the plastic part that holds the strings off of it is falling apart. I measured it and it is 12 1/4 inches. What would be the correct size I need to match the original, or does it matter? I also measured the tailpieces off of my Kay, which was 13 1/4 inches, and my American Standard, which was 11 1/2 inches. Also, what kind of wire do I need to go with it, length and type? Thanks for any help.
