It is not all that hard, just time consuming. If you don't have AC then just drop your glovebox and the access panel is right there, straight forward. Having done this a couple of times there is no real "short cut" About a 3 hour job, the dash comes apart one piece at a time and is pretty straght forward. Big thing is to baggie and label screws as well as vac lines. PITA when you are looking for where things go. Some people recommend the FORD unit, me I figured they screwed it the first time what is to stop them a second, so in went a unit from Pep Boys. 20 bucks or there abouts. Put JB weld around the in and out tubes this way you will not have to be REAL careful hooking the heater hoses back up. You will see that there is not a whole bunch there. It will take you about 3-4 hours to do. The only "special" tool that was needed was those star screwdrivers. Ford will charge you about 400 to do the job.
Try doing a search on the boards, there was a guy awhile back that put out some awesome detailed instructions on this.
