Hi Andy,
The B2A was made between 1985 and 1993 in Korea. Your serial number #8701044 indicates that it was made in 1987.
Great to hear that you already checked the C-Shop. All the parts that we can provide are listed there. So, unfortunately, if you couldn’t find the parts you needed, we do not have them any more. Maybe a specialized guitar shop or a second hand guitar shop can help?
Thanks for your understanding.
Kristin
