Once I routered the cavity to get good alignment I decided to go ahead and make a cavity to relocate the bridge pickup.

Keda dye and tru oil finish coming.
I'm trying to decide if I want to put in Jaguar style 3 switch plate to control pickups. Some years of bass VI had 3 without the strangle. It would nice to have the control. A humbucker in the bridge might be nice too.
