This truck is a 2wd and has 5 X 4.5" lug pattern and 3.25 9" axle. I would like to upgrade to a limited slip axle and disk brakes. Did the old Lincoln cars have limited slip axles? Does anyone know where I can find of list of possible "donor" cars for this project?

Also, what is the difference between a F100 and F150 truck in the 70's and 80's?

Your help is greatly appreciated & thanks for reading.
