Pickup Spacing on Gretsch Broadkaster and Thunderjet

I posted this in the general "Basses" sub-forum and realized my question is probably more suited to this sub-forum.

I would be immensely grateful if someone who has a Gretsch Broadkaster or Thunderjet bass could measure the distance between the two pickups. I would be even more grateful if someone could send me or post a tracing of their pickguard.

I have a Gretsch 5123B, which comes stock without a pickguard. I'm trying to find out if the Broadkaster or Thunderjet would be a suitable template for making a pickguard for my bass.

Thanks!
