Geeze, it's only 6 bolts. The secret is to remove the stuff in front of it and to the sides. If it's a 97+ then you DO have to loosen and remove that power steering bracket bolt that goes to the block.
Use a good sharp scraper on the old pumps mounting surface on the block.
Get a small bottle of Indian head gasket cement. Wipe the side of the new gasket that faces the pump and lay it down. Use a screw driver to line it up with the holes. Let it set for a while then put a thin wipe of the same stuff on the side facing the block. With the electric fan, brackets, etc out of the way put the pump on and start the bolts, keep pressure on the pump so the gasket does not pull away. Tighten the bolts finger tight [I use a finger ratchet, great gadget]. Once you have them snugged up take a 3/8 ratchet and snug them up a bit tighter, alternating between bolts just like on a head or wheels. Then take a 3/8 click type torque wrench and torque the bolts down to 22-24ft lbs. At that point you can then reattach the two power steering bolts in the front. At that point you can then put that single bolt back into the back of the power steering bracket where it goes into the block. Oh and the biggie, make sure any water, coolant or moisture is not there, keep that gasket dry. I used a baster to remove the coolant from the block where the pump pokes into it by the front cylinder jug. Probably pulled out a quart of coolant then dryed it out with rags.
If you don't remove the ps bracket and try to snake that pump/gasket behind you WILL screw up the gasket and at the worst possible spot where it is thinnest. You definelty have to get that pump/gasket to go straight in and hold it in place while you snug it down. I just did mine couple weekends ago and messed up one gasket on sat and spent 3 hours on a sunday finding another one.
