Hello Wilfred,
I apologize for not noticing your request the first time around. It's been a hectic 2 months.
Anyways, to answer your questions, yes, we can make you a brass plate for the electronics and for the truss rod cover; pricewise, I'll have to e-mail you tomorrow, since I'm home now, and don't have a parts price list handy.
In regards to your second question, I guess we could, even though we've only done it with new basses; Susan, of course would have to approve it.
I presume you'd want to use the pickups you have on your bass now? In that case you'd have to be prepared to be without them for a few weeks.
I'll check with Susan, and see if she consents and at what price.
Valentino
