Modern Thunderbird / Vintage Conversion Project (a few questions)

[dc10bass]

Alright…
So I am finally going to cave and get this once dead project going again.
…Wouldn’t mind some input from the fellow TBird obsessed.

I have a 2003 Gibson Thunderbird bass with a broken headstock.
The plan is to have it replaced with a larger vintage style headstock to support original style chrome tuners.
…Also going to add;
•   A two piece bridge
•   Chrome pickups & Pickup Rings
•   Reposition the input jack from the side to the front of the body

1st Question:
Are the locations of the pickup cavities different on a 1964 TBird compared to the modern TBirds?
…If so, where are they in respect to the 12th fret?

2nd Question:
Two piece bridge location… where are they in reference to the 12th fret?

3rd Question:
Plug the three current bridge holes “OR” remove a portion of the raised body center and add a new center laminate?
I recall seeing a thread somewhere where this was done…
...the center portion was taken down up to where the seam would be hidden under the bridge pickup chrome ring. I recall that it looked good.

Any input would be appreciated…
THANKS!

Re Q 1
iirc George has a pup position picture with the dimensions laid out - it's been posted a couple of times...?

Re Q 2... it was in the wrong position, so do you want it that "accurate" - I can give you the dimensions off my PC but I'm sure others will have them to hand...

Re Q 3
Sounds adventurous... () presume you are not going for a solid fin...? a plug is an awful lot less work but it depends on what you are going for...

Good luck...

I can't answer 1 and 2, but filling the old bridge holes (take the inserts out and plane off a little of the center piece to compensate for the new veneer)  and covering with a new veneer isn't that hard, just time consuming.

Nice one... thanks for the input.
Sounds good, that is the plan for the bridge holes.

Forgot to say fill the bridge holes.  Also was wondering what kind of replacement bridge are you using?

[drbassman]

I was thinking about a two-point bridge.  You probably wouldn't have to plane the center block if you're using a two pointer.  A mm or so wouldn't make a lot of difference at the center.  You'll have to sand it down anyway for the veneer application.  As long as a veneer wouldn't raise the center appreciably high, it won't make a lot of difference since the bridge won't be resting directly on the center block.  Neither do the pickups.

Sure, I knew that the holes needed filled either way... was just on the fence about a new veneer.

If there is a significant difference between the pickup locations (vintage to modern),
I may fill those, continue the veneer, and reroute the pickup cavities.

I have a couple (new) retro tail pieces and one two-point bridge.

Thanks
