How hard is it to change resevoir seal on a Federal pump on a 73 400 Charger?

My 73 Charger is leaking oil from a couple places. One from the oil pressure switch, somewhere on the transmission and the worst one is from the power steering pump resevoir. I replaced the pump with a reman back a couple years ago when I put in the motor. I just hate taking all those belts and brackets off. I'm assuming the pump will have to come off?

I am doing mine right now, not hard at all.  You will need a rebuild kit and the special tool to pull the pulley.  After the pulley is off the reservoir just slides off.
