Here are mountspacing and string spacing and Pickup ID with photos and links. Look no further. More info below. You may access this off site: spreadsheet.
This has developed from just Trems to pickups too. This sheet is a constant work in progress. You may also contribute with data if you have any of the guitar with missing specs. Use the chat or access the spreadsheet offsite and leave a comment there if you wish to add or correct things.

2-3/16 = 55.6mm (Japan)

2-7/32 = 56.3mm (USA)

2-1/16 = 52.4mm (Mexico)

FSR= Fender Special Run

Some partnumber might re-direct to a tremolo with different part number. You should not worry as i probably list the original number. But Fender did change the Product ID# on a few but the specs and model is the same.

----------

Custom Shop guitars are not listed. The majority of them are Vintage bridges. And the severe limited run of them gives me less reason to list them. I could make a spreadsheet for them only. But it would be entirely user-contributed. Let me know.
Floyd Rose models are NOT represented on this list yet. But i will probably get to them later.
