I just recently picked up a unmolested 92 Convertible 4cyl auto. I have the chance to buy a 94 GT that isn’t currently running but has an Auto and I plan on rebuilding the motor. My question is am I right in being able to swap the suspension and upgrade the brakes and put it on my fox? Also what other parts can I swap over to the fox to upgrade it a little better?

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

Use it all off the car . Max MOTORSPORTs sells the adapter fitting you need for the front driver side brake fitting .

Use a 93 cobra booster with it .

Rear - pull the axles . Get north race cars caliper brackets and use fox length axles with the 94-04 flange to keep the track width same . You can use the calipers and all that off the donor car

Get the max Motorsport brake line kit for the master cyl to adapt the proportioning valve and swap the fox 3 lines to 2 lines .

Also have to gut stock prop valve . Get the solid front plug . Install adjustable prop valve at union on pass fire wall

@Mustang5L5 any other advice I’m missing . Can he use e brake cables out of the donor as well ?

He can but he'll need to remove the cable mount braxket in the trans tunnel and tack weld it into his car.

Might be easier to buy the conversion cables from LMR

I personally wouldn't pull a 94/95 engine and rebuild it.
I'd rather just buy an explorer gt40p engine, likely it's not beat to death (they are hard to kill anyway), so at least for your effort you get gt40p parts.
Or find a complete fox engine.
Rebuilding and dressing the wrong engine could get time consuming and expensive and you will land up something no better than stock.
Just too many steps for something mediocre, considering you have no core fox engine to start with.

If the price is right, the 94/95 is good for the brakes, but imo the engine and trans are worthless.

I did find this running 94 GT and I feel really good about the swap. I got the whole car for a steal of a price and traveled almost 700 miles to get it. I’m not too worried about the fuel injection because I think I’ve got myself talked into going with just a carburetor setup. My Convertible sits really low so can the GT springs be used Since you say the shocks and struts can’t be?

IMO, that is a [lot] of ass pain to go through for a set of heads and intake that'll end up on ebay or sitting on a shelf somewhere but I do see your point.

I'd have no issues whatsoever rebuilding that 94 engine but I have been at it long enough to know that Windsor OEM heads are near useless (we could debate the extreme cases elsewhere).

With all the trouble necessary to swap everything over and convenience of having a donor car, a couple extra bucks for some nice aluminum heads would certainly be in the future. Even if they were a worked over set of used aluminum heads.

I don't really disagree.
You know how i feel about gt40p parts from a performance standpoint (i see them as boat anchors for the most part)
Just with no engine at all and i'm getting the feeling that this is a budget project that isn't going to get aluminum heads, i figured at least for the trouble of tracking down the front dressing setting he could get an extra 30-40rwhp or so.

As for a pain, most junkyards in NJ don't really let you pull the engines. Be much simpler because they may deliver it or just have it ready for you to pick up.
The front of the engine still needs to be swapped out regardless.

I personally for the project would want to start off with an engine that came from a foxbody that is complete.

Not sure it matters he says he may go carb, which is something i hope he rethinks, i can't imagine going through all this work and using a carb.

This could be a really sweet Vert but it will require a plan and some dedication, to be sure. It looks like the body is straight.

I agree.
That's why i'd like to see him get a factory harnes and computer instead of a carb.
I would like to do the factory harness but I’m doing this all on my own 99% of my friends have no mechanical skills at all and I don’t trust myself enough to get the fuel injection right

It is very straight minus the front bumper cover. The top does need replaced but was expected when I first seen it listed. Interior is all there and in good shape except the ash tray cover is broke and the rear speaker covers have a few cracks. It is very solid and couldn’t have asked for a better project for me and my 5 year old daughter to work on together.

Why do people always use the "I would but a carb is easier" reasoning. Electronics are literally plug in by very definition. I had a '66 F100 and a wrecked '90 Mustang GT once. There was no forum then....or public internet for that matter. So I winged it. I pulled the engine and AOD out along with the computer and engine harness. That's the whole harness from the computer to the engine. Put all of that in the truck and drove that truck for several years. It was one of the first fuel injected late model swaps I'd ever seen. This was in '92. I never worried about a cold starting carb anymore. The truck was so much better to drive with the fuel injection.

Why do I say all this? Because all I did was unplug, plug, unplug, plug....and keep going till everything was connected back like i removed it. I also had my Fox body there if I needed to look at something. Now we have the internet and this swap has been done a million times and documented. I don't hate carburetors. But I certainly don't want to depend on one. Consider the EFI. Lots of us will help with anything you need. Do it one time and you'll see it's not a big deal. Ultimately your call. I've said my peace. :)

I might give it a shot and I appreciate your input

It’s a plug and play deal to go back to stock fuel injection . Carb is not the answer and in reality so much has to be done to do it right - it’s counter productive
