The link to the spreadsheet is dead.
I slogged through the 20 pages of that thread.
At the 1st, 3rd and 12th frets the girth (circumference) of 4004 necks ranged from 11.4/11.8/13.4 for '93 4004C and 4004L, to slightly larger for a '95 4004C (11.35/12.0/13.8 ), to a high of 11.8/12.46/14.23 for a '08 4004Cii.
(All measurements in cm.)
No measurements of neck width and front-to-back in that thread, other than the '08 4004Cii:
width at nut: 4.41
width at 12th: 5.77
front-to-back at 1st fret: 2.37
front-to-back at 12th fret: 2.53
With only this very small amount of evidence, I can say that
1) the necks of 4004Cs and 4004Ls of the same year likely have the same dimensions
2) the '08 necks were large
Can anyone add more data for 4004-series basses?
