The 4-lug rotors will only work with the Fox spindles, and SN95 calipers won't bolt to the Fox spindles.
Not sure what Lincoln you're referring to, as there are lots of Lincoln models out there. The Mark VII front brakes were the same as the Mustang GT, just used a larger piston in the caliper. There's little to be gained there since it's still an old caliper design and a small rotor.
As aurdaco said, do yourself a favor and start budgeting for an SN95 swap. It's not that expensive to do, and it opens up sooooo many more options for upgrades in the future.
