Get someone to build you the wood bits - there are plenty of guys on here who would do it. Buy the hardware on here. Every pickup ever made crops up eventually. Get https://www.facebook.com/Retro169?fref=ts to paint it. I am in the process of doing this with a J5 http://basschat.co.uk/topic/192744-relic-j5/page__p__2062347__hl__relic__fromsearch__1#entry2062347
If Bravewood built a J5 I would have him doing it, but he does not, so I am getting it done another way.
