Use the front spindles and brakes, get the aftermarket axle housing brackets for the rear calipers, (the 94 rear is wider), and swap the rear brakes, you'll need 5 lug axles, or get a kit for the conversion, use the 94 MC to be compatable, others here will tell you what brake booster to use, I don't know off hand what you need to do for the brake hardlines. The front
control arms are shorter on the fox than the 94, so you can't swap them, get the ball joint spacers, or 94 ball joints for the stock arms. Some will tell you, you need to go with Cobra 13" rotors, you don't, 94 four wheel disks are vastly superior to the fox brakes, cobra 13" rotors are just another step up. The
suspension is exactly the same except for the front
control arms, shocks, and struts, (slightly shorter on the fox). If the 94 is a real bargain, that's the way to go, if everything is usable. if you end up in the salvage yard, or buying a bunch of new parts, maybe not so much. Some changes will need to be made to the motor, the 94-95 5.0 intake is different, as is the front dress, (timing cover, water pump, all the brackets) you may be able to use this as is, I don't know. The 94 is also set up for an electric fan, so that will need to be looked at. Wiring will also need to be considered, I dunno how much of the 94 wiring you can use, or for that matter how much of the 92, you will need the 94 computer, unless you convert the EFI to 93 or older standard. I'm sure there is more, this information is based on what I know about the differences between the Fox Mustangs, and the 94-94 SN95's. Good luck with the swap
