That would be very helpful! I just confirmed with TV Jones that the Filtertron PUs fit their trim rings, and the dimensions are shown at:
http://www.tvjones.com/tech_specs/techspecs.html.
Their tech pages are very helpful and contain a ton of info - more than I realized.
My idea is to make brackets something like this:
Top
__X__
|
|
|
|
|__X__
Bottom
With each x indicating the location of a threaded screw hole. If the top end lines up under the mounting hole in the pickup surround/trim ring, the bottom hole should line up with where the mounting screw comes through the pickup.
My first concern is to make sure the TV Jones mounting rings will cover the original mounting holes - these pickups are alightly smaller end-to-end. If they don't cover, I guess that I'll have to have custom mounting rings made. Now that I have the dimensions I can measure the setup tonight.
I just looked up some 6072 pix online, and the pickups do look like Filtertrons - but there's no mounting hole in the ends of the rings. I am really curious as to how they did mount those pickups - I'll bet I'm missing some really simple idea!
Edit: hey, Bill...check their videos linked to the Tech Specs page. Down at the bottom is one called "pop those shims", which shows a wood brace under each side of the pickup hole and a wood shim between brace and pickup. I wouldn't be surprised if that's how your 6072 PUs are mounted.
