It will bolt up to the engine w/o problem. Like you said, fabbing the crossmember isn't too hard. Drive shaft will probably need to be custom made.
The shifter handle is too short for a truck. Putting it in the truck makes the knob kinda low. Use a short throw shifter and a longer handle. It will shift like a truck, not a Mustang.
The tricky part will be the clutch linkage. Linkage in the 60's was a push rod affair. '95 parts use a cable pull. You'll have to adapt a cable linkage in there. SOmetimes easy, sometimes not. Or you could spend big bux and use a hydraulic ram or hydraulic throw out bearing.
