Even if you fitted them with custom bushings to work on the Ford axle, or went the other direction and bored the axle for the Lincoln king pins your camber will be off. Ford king pin inclination (the amount of difference from 90* to the axle stub) is 8* and the Linc is 4 1/2*, you would have about 3 1/2* negative camber. Plenty of Ford spindles out there, either '37-'41 round back or '42-'48 square back.
