Been there and done that.
It should be a law that trucks have a body-lift; as, it is unreal how much easier everything is to get at and work on.
Somewhere, I have the measurements for bolt-lengths.
The lift blocks are merely some kind of plastic spacers.
Unless the truck is an automatic, nothing on these Fords has to be addressed, except to cut off the bottom half of the fan shroud, before you start.
Also, I made a simple flat steel bracket for my parking-brake cable to pass through, instead of through the cab-mount brace that it currently does before lift.
I think the brand-name of the kit I bought was Superlift.
It is really very simple, with longer bolts, and plastic spacers.
The only reason I bought the kit is that I did not know how long the bolts needed to be, and I was doing this after hours, when all the hardware stores were closed.
I initially went up three inches, but this brought on two issues.
1. I know this sounds crazy; but, at three inches, part of the cab came up into hard contact with the rear of the engine, or bell-housing, and turned my truck-cab into an echo chamber. The place that was interferring was impossible to access and would not move with forceful applications of long crow-bars.
2. At three inches, the steering rod came dangerously close to coming out of its slip-collar. At two inches, it is only out about 3/4".
I removed the spacers and sawed them back to two inches; and, I was able to swap around the bolts, between the kit bolts and the originals, to come up with a set for the inch lower lift.
I recommend getting a Borgeson, or Flaming River, steering shaft; I am soon getting one; I have put about ten thousand miles on the body-lift with the stock shaft with no problems, I just like the security, and extra slip length, of the Borgeson.
One thing you will run into that will near make you crazy is the front mount-bolts that go through the radiator support.
You cant see this, but the bolts are threaded through the big washers that clamp down on the rubber cushions.
You will remove the nut that makes sense and beat and hammer and cuss and cry; but, until you have someone with a big pair of channel-locks hold that washer and turn the bolt out of it, it ain't going to come loose.
Weeks before starting, crawl under there, twice a day, and drown everything with knocker-loose.
If you buy a kit, simply make the extra spacers necessary for a crew-cab, and buy a few more bolts; also, some 7/16" all-thread on hand would be advisable for un-foreseen circumstances.
I posted the bolt lengths on another site and will try to find them for you.
These kits are so simple that you can make everything needed easily.
One more thing, don't use the red thread sealant that comes with the kit, as a torch must be used to get it loose; the cab-cushions keep the nuts under tension, so they aren't going to back off, anyway.
Any more questions, just fire away.
