OK, parts came back up but I'm not finding a breakdown for the F-7 mechanical in PS3.
Tip- when searching for pickups, the listing might be with hyphen so I just use "pick" and then refined with "double" for the F-7 style as shown.
You then can click on the picture icons and also measure and compare yours. Specific other details, yours are insulated rollers on the ends (so they don't show out switches and activator tracks)
