I've had your bass on hold while we figure out exactly what you want on this bass. I checked the file for your Red Tiger bass, and the fingerboard is 1.4 x 2.25 strung with your supplied Rotosound strings in gauges .030 .040 .060 .080. Here's how those details compute with our normal style of side-to-side spacing at the bridge:
###############################################
id = shoji's re tiger bass
scale length = 30.75
string dia. 1=.030 2=.040 3=.060 4=.080
at nut end:
fingerboard width = 1.4
treble edge allowance = .15
bass edge allowance = .15
string center 1 to 2 = 0.348333333333333
string center 2 to 3 = 0.348333333333333
string center 3 to 4 = 0.348333333333333
spacing between 1 and 2 = 0.313333333333333
spacing between 2 and 3 = 0.298333333333333
spacing between 3 and 4 = 0.278333333333333
at bridge end:
treble edge allowance = .15
bass edge allowance = .15
string center 1 to 2 = 0.705
string center 2 to 3 = 0.72
string center 3 to 4 = 0.74
spacing between 1 and 2 = .67
spacing between 2 and 3 = .67
spacing between 3 and 4 = .67
string edge to edge = 2.22
(projected) fingerboard width at bridge = 2.52
fingerboard width at nut = 1.4
fingerboard width at 24th fret = 2.24
fingerboard width at 25th fret = 2.25571519244913
fingerboard length = 23.4939662212595

If you notice, the strings are slotted center-to-center at the nut where you aim for the center of the string when you fret a note. At the bridge end, the dimensions shift to side-to-side spacing since you generally are aiming for the edge of the strings with that hand. There is no notation on the order for Red Tiger that the spacing was ordered as spaced center-to-center at the bridge, so I'll assume that it was done in our normal side-to-side fashion. You can compare the measurements and see if the spaces between the strings are close (with a couple of thousandth of an inch) to confirm.
To make the bass like you requested at the top of this thread, the fingerboard would be 1.4 x 2.21. The details are here:

So, after all that, I need to know from you:
1. which spacing style you want on this bass (side-to-side or center-to-center at bridge) and the space dimension.
2. are you supplying strings again?
