I picked up an fbody pan setup(98-02) because the ground clearance is much better than the truck pan(about 3 inches). As for the accessory drive, the f-body setups are a bit more compact for radiator fan clearance. Also, I prefer the appearance and they aren't terribly priced. I've been looking at the Dirty Dingo setups.
I went with the power rack option. I was a bit surprised at the cost of the powersteering pump. Realistically, once you get the pump, hoses, bracket, and pump pressure lowered for a mustang rack... you are looking at ~$500-600 extra over a manual setup. Which was a bit of a pill to swallow, but at the end of the day I think it is one of those things that makes you want to drive the car more.
For cooling I already had a be-cool aluminum radiator and my dad knows a guy who can add a port to it for the steam port. So I'll likely just add an electric fan setup to it. I recall one of my friends mentioning that a ford windstar electric fan setup is pretty inexpensive, but decent.
If you get a 408 stroker in yours, I will be jealous.
