Ok my problem was I couldn't get the new serpentine belt to go on because the pulley was too big. So if I buy one that says it works with the 4.9, 5.0, 5.8 I should receive the smaller pulley right? But if I buy one that says it works for the 4.9 and 7.5 I'll be back in the same boat with the bigger pulley I would assume?
A/C - Increased Refrigerant Charge
Article No.94-19-20
09/21/94
AIR CONDITIONING - INCREASED REFRIGERANT CHARGE - VEHICLES BUILT THROUGH 8/30/94
LIGHT TRUCK:
1994-95 BRONCO, F-150-350 SERIES, F-47
ISSUE:
Ford Climate Control Division has increased the refrigerant charge in the subject vehicles from 2 lbs. 1 oz. to 2 lbs. 6 ozs. Also 94-97 trucks call for 2 oz of oil additional over the service data.
ACTION:
When service to the A/C system is required, recharge the A/C system with 2 lbs. 6 oz. of R-134a. Make the necessary corrections to the 1994-95 Service Manuals, pages 12-00-35, 12-03A-58 for 1994 and 12-00-39, 12-03A-56 for 1995.

Do you have the switch?
It screws on the *** end of the line set. Post more pics when you can please. Can always jump the switch easy enough

See that cap? That is where high side switch threads, as I stated...Make sure the scheader valve is actually tight. Been there and done that.
Yah, you need to acquire one if you want to use it or just jump the SOB.

I got the 980k6 duralast belt from autozone says effective length is 98.0. It's still too short. Says it fits the f150 4.9 with the a/c. I got the new compressor with the smaller pulley. Some how it's still too short.
I'm also installing it the way the diagram on the truck states.
Never had this problem installing belts in vehicles before
Any other belts you guys recommend?
