good stuff Ben, an ash tray style bridge,that will look hot.
I'd put the kit bridge pup in and do a mock build and please post distance nut to centre of 12th fret and centre of 12th fret to both E saddles.
Worth checking if you need to route the bridge pup cavity further north
I love the service at Realtone too, if I order morning on a weekday usually receive the parcel 2 days later to Perth if using express post !
