I just found this thread but I can contribute a bit...
This is a Vista that was for sale on ebay, and I just flogged the pics.

This is a Gen II jaggy that I was gonna buy about a year ago. I think it's also CAR, but hard to tell. I think it's just a poorer quality of CAR.

As for measurements, my jaggy is still off getting modded (will be done by next week, so I am told) so I can't help much there. but what I can do is post a couple of photo's which give some idea about fitting jazzy pickups.


I think I flogged these pics from this site. Taking a look at the neck pocket compared to the size of the jazzy pups give some indication. I am 90% sure routing would be needed.
Hope this helps, I can't post much in the way of measurements until I get my own back.
