Justs did mine on my 89 SC....
The first time you work on these, it may seem hard, but it is more time intensive than anything else.
Myth one is that the accessories on the passenger side must be removed. There is nothing on the passenger side that must come off. In contrast though, the entire drivers side must be removed, with the exception of the lower intercooler tube (unless you want to reseal the tubes, not a bad idea while you are in there). To get the Power steering/alternator bracket off w/o removing the lower tube as well, use a 15mm deep socket to remove the nut holding the lower intercooler tube to the p/s bracket. Once that is out, use a 7mm socket to remove the stud from the p/s bracket. I think there are 2 more 15mm bolts and one 15mm nut on a stud that need to be removed, along with the alternator and the two nuts that hold the bracket to the water pump studs (13mm I think). After those are out, the bracket should slide forward and off (oh yeah, it is also a good idea to remove the intercooler and give her a good cleaning with some acetone).
Of course you will have to remove the harmonic balancer (evil thing from Ford), crankshaft position sensor, cam sensor, crankshaft position sensor bracket, and the rest is pretty obvious.
If you need any help at all, please let me know. Like I said in the subject, I just barely finished this last night. It is very fresh in my mind still.
You do it once and the next time it is a piece of cake.
