Dropped the above into my jag and it's been great so far.
I bought this and moved its saddles onto the stock bridge
It's probably not super good but it's a lot better than the stock "worst bridge ever made"
If you DO want to go the "mustang" route, opt for this unit:
Reason being, the mustang bridge doesn't have an adjustable radius, and the mustang radius isn't the same as the jaguar.
This bridge has fully adjustable saddles, so it can be made to match any radius.
Though, this may or may not be more or less exactly the same as buying a $15 bridge off amazon, and using its saddles (or whole thing). Not sure how the quality differs, but the function is the same.
