    Hey guys my name is Harry Montgomery and I have a 88 gt that I am about to swap a 03/04 motor into. I also have a 96 cobra parts car that I am going to be installing the cobra brakes as well as the cobra rearend...I am at a cross road before I start. My buddy has a wrecked 03 cobra low miles that I can get the dash, console, door panels and that kind of stuff. He said if I pulled the dash I could have it and the harness behind. I am already getting the 03 computer as well as the engine harness and cluster. Is that all the wiring I would need just the engine harness and the dash harness or will I need the body harness as well to complete the swap. As of now I'm going to pick up a 3650 tranny because the t45s I have laying around from other 96-98 cobras will not work with the newer cluster. Trying to get my ducks in a row before I get deep into the project. I am in the middle of building the motor I have a 98 cobra teksid block with Kellogg crank and the svt manley h beams all arp hardware....still tracking down all the swap parts have a big list but still need more...here is what I have so far....(03 dual fuel pump setup, blower, metco 4lb lower, engine pulley set up, heat exchanger and lines with intercooler pump, 03 39lb injectors, fuel rail, mass air meter with sensor for 39lb, intercooler tank and within the next few days have the ecu, engine harness, and dash harness) Long process but will upload pictures as I progress in the build...any tips would help greatly

    I know with some wiring I can reuse the existing fox dash and wiring but really thinking about the new edge dash and interior swap

    Hi Harry. Welcome to the site. Dig in and make yourself at home. My advice for you is that if you're going to do the dash and door panel swap, get all the associated wires that attach. Basically get everything you can. Having it all from the same donor makes the job a bit easier. I'm looking forward to seeing those pictures.

    Thanks bill...long process but I have a 99 cobra t0 drive and a 85 gt so at least I can still enjoy my mustangs while this one is down for the count....ill upload pics as I progress and thanks for all the support. I am sure I will be asking lots of questions as I'm new to modular swapping foxbody's.

    I almost hate to part mine out, as it is a Double X Cobra, meaning it was a factory demo model that really did put out 320 wrhp (which is why Ford got sued over the ones the delivered that year). It is also a four time looser. The third time it was wrecked, the assholes didn't fix it properly. So, the next time it was wrecked it bent the frame at the firewall. It still moved under its own power when I bought it at a salvage auction.

    man shame to part it out but at least it can go to use for other people or for your own cars.....I was the same way with my 98 cobra parts car 80,000 miles and totally rust free but the previous owner blew the brand new motor and pushed outback of his house. When his buddy wrecked his 98 gt they took the drivers fender door and rear quarter off to fix the gt ughhhhhhh and left it to sit...I came along got the car complete minus the drivers side parts and a spare 96-98 cobra motor for 800 bucks lol

    You can get all of the wiring from Midway Mustang. Go to Facebook or Instagram for contact info.

    if youre doing the dash, youre doing the steering wheel too. unless you are a splicing genius. if youre doing the steering wheel, you will need to figure out the bearing that penetrates the firewall.

    grab a drill and start drilling out that firewall plate that has the bearing. might as well grab the brake booster too, the fox one wont clear, I dont think.

    Yes I will be doing the dash as well as the cobra steering wheel since it will have the cobra airbag....I will also be converting to the hydroboost brake set up and cobra calipers

    Sounds like you have a good setup. The bearing for steering shaft is actually pretty easy. Take the entire plate from a donor car by drilling the spot welds. You'll have to notch the lower left (driver's side) corner of the plate to fit around the frame rail. There are a couple of pictures on here that are nicely done. Using the complete plate gives you lots of meat to mount with and makes the bearing wall nice and stiff. Whether you weld it in, screw it in, or rivet it, don't forget to put some good body sealer on the seams. That section takes a beating from water.
