1. Leave the string spacing at the default value of 1.6 x 2.15 (nut x 24th fret). This calculates to a bridge spacing of about .57 inches between the strings.
 
Thanks Mica!

Hi Mica,  
 
As you are surly aware, the battery compartment for the 1976 Short body Series I, is located along the the solid neck through area.
 
If possible, for the Toma_Hawk, I request to keep the neck through free of any cuts for batteries or any electronics (if possible). I am not sure if we discussed this, but I aware from looking at other basses (Series in particular) you guys don't cut through the neck anymore... Just checking to make sure.

We discussed this by email, but the battery location has to be on the neck, especially in the abbreviated custom body shape on your bass.

Yes, I agree.
 
Battery on the neck is old-school cool  
 
No changes.
