Ford manual and automatics take a different starter. You will need one for a manual. The clutch is also different size between the cars and trucks(from what I have seen). The cars generally have a 10" or 10 1/2" clutch while trucks use an 11" or 11 1/2" clutch. I'm not sure if you can even bolt a car sized clutch onto a truck flywheel.
You know, the cable operated clutch isn't all that bad. You never have to worry about air in the lines or a master or slave failing.
