I thought about the neck transplant thing, but I would love to try to save this neck. The shaft is flamed maple and the fretboard is rosewood. Yesterday my wife and I attended a friend's funeral and I ran into another buddy of mine who (I didn't know) started a custom guitar company during the COVID lockdown! He said "bring the guitar to me and I'll reproduce the neck if I can't fix it! Wow! Prayer answered!Welcome. I can't help you, but good luck. If it were my project I would plan the time and budget to find an intact instrument and do a neck transplant.
You can tell us why you are looking. There may be other options and we can cheer you on.
