Yes, they will fit all around, but be sure and do your research before you buy.
There is nothing worse than throwing money down on a set of wheels and then they aren't offset just right, or tuck into the fender well lip too little or too much.
First I suggest going with an 8" wheel up front and a 9" out back.
My suggestion, if you want chrome, is to buy the FRPP 17x8's for the front with a 245/45 tire. These wheels are perfectly offset/backspaced for the front of a fox body (+15mm/5.15"). You can buy these cheapest at
www.gefracing.com
For the rears I suggest the Verde 17x9 Replicas as these fit just right with the rear fenders and tailpipes when running a 275/40 tire (+18mm/5.71"). You can buy these at
www.mustangtuning.com
The only other suggestion I can make to you, if you want to buy silver, is to get the OE Concepts 17x9 for all around (+20mm/5.77"). You can buy them right here at partsshopper for $114 ea.
Here are some pics for your visual reference:
First notice how this 17x8 AFS wheel (+12/4.95") just doesn't tuck properly ... it isn't offset correctly, yet AFS claims they fit "perfect"

Ford's 17x8 ... notice how they fit just right up front ... yet they ARE too tucked for the rear.

Now look at these Verde's with 275/40's mounted ... they're just right for the rear ... yet they DO protude out too much for the front. (You could see better if the tires were straight in this picture.

And finally, heres OE Concepts 17x9's all around with 255/40 & 265/40 rubber ... a little snug up front, but with a little massaging of the fender lips they fit and look tough.

First and foremost, make sure you like the look of the replica, as they all have slight design differences.
(Sorry to anyone that owns these cars, but they're great for visual reference.)
