You need to specify what kit it is.
There are a few ways to get 5 lugs.

Generally speaking 5 lug setups are pretty easy to install.
If all the parts are present most of them will be self explanatory and only go one place.
Getting the c-clips out of the rear axles is where you will likely need the most help. So do a few searches on that topic.

yea i think..the rear is where im going to spend most of my time...the front should be realatively easy...however the rear of the car is where im most unclear....like how to remove the clips and how much gear fluid to put in...

as far as the kit.. im buying it from someone locally he tells me that the spindles are from a 2001 mustang.. and that im going to need an brake line extender for the passenger side...

I'd rethink this purchase, the correct spindles for the swap are from a 94/95.
Ya, you can make others work, but at the expensive of different rims.
Also attempt to do the rear with fox length axles, not 94 or newer ones. The newer axles track wider and also cause rim fittment issues.

IMO, just piece it together yourself.
If you can't afford all the good stuff at once, do the front first, then do the rear with ranger axles and drums until you can get the proper parts for discs.

I got pretty much the same thing you are looking at. I sold the newer spindles and got the older style though (94-95). If it is all off the same car, nice thing about the kit you are looking at is the calipers being the dual piston pbr's (some grinding of the spindle is necessary). The newer length axles worked great for me with the bullit rims. I custom made the rear brake lines on the axle. I went back and forth several times to find the correct adapter for the fronts and MC but it was really pretty simple. The pedal is a little soft for my liking, I am running a 94 MC and a 93 cobra booster. Also make sure you pick up and adjustable proportioning valve. There are many write ups out there for you to go by but if you go through with the deal and need help I have a ton of pictures I could probably do some kinda write-up for you. But honestly if I could figure it out, anyone can.

Here's a few pictures to maybe give you an idea how mine went

I didn't really get a good picture of them. if you look at the picture I put up of the differential, you can see about a 1 inch diameter rod going through the assembly. there is one small bolt holding that in (maybe 10mm or so head IIRC). when you remove the bolt, pull the rod out. then push each axle in toward the differential and you will see the c clips clear as day. That was the first time I ever took one appart and i couldn't believe how simple it was. just make sure to not move or turn anything once the axles are out

Having just completed this operation (with some great help !) let me say there is a great deal of planning involved even though turning the wrenches can be fairly easy. You have to decide which "way" to go, used parts, new parts (or a combination thereof), Fox parts and track/width, or SN95 track/width. A lot of guys just get an SN95 rear end complete with the rear disks from a J/Y. I chose to stay with my stock differential and started with as many used parts as possible (Ranger axles and drums, SN95 front spindles, etc). This got me in the 5-Lug game fairly cheaply and allowed me to spread out the work (and expense) over about a month's time. We did the front spindles/disks and rear Ranger axles/drums one weekend and several weeks later ordered the parts for the Cobra rear disks (using the North Race Car adapters) and put all of that on another weekend. Plus I was able to keep the Fox rear track and use 17 X 9 wheels and 275/40 rear meats !

I agree as already stated, the 94-95 front spindles are the ones you need to use. Also, a small magnet works good for removing the C-clip when the time comes.

To me, it was a real educational process. Just read all of the articles you can until you get the full picture of what all is involved and which way you want to go.

very well said blackgt, planning was a huge part for me as well which is why I ended up with the cobra brake booster. I ended up using alot of the parts I bought as a kit for cores and i bought new stuff. The axles I am using are off a 94-98, I just realized i forgot to say that the 2001 axles are even longer than the sn95. If you plan on running those rims you posted up you will be most likely fine with the sn95 axles but anything wider you may run into issues depending on your ride height. I am using weight jacker LCAs so I was able to adjust. I am running 2001 Bullit rims with 265 40 tires with no rubbing issues.
like he said do lots of planning and research for what you want.

ya you will probably run into some issues in that case. With my LCAs lowered all the way (about 1" lower than factory) I was rubbing pretty bad. My 265s are wider but your 235s are taller. Who knows maybe you just sneak it in there with rolling the fenders, but you are pretty low. Personally I'm a fan of a nice aggressive looking rake so my rear is set at about factory. But if you want to stay low like that you should look into ranger or aerostar axles with North Racecars brackets. You will need either 83-92 Ranger driver side axle from a 4cyl or 3.0L V-6 with the 7.5" rear end, or 86-97 Aerostar passenger side axle. You cannot use both axles off the same vehicle because one side is longer than the other. The length you are looking for is 29 5/32. Or if you are rich unlike me you can buy new ones!

I should mention that I'm at stock ride height and I did have to reverse my quad shocks to clear the rear tires. Even at that my quad shocks are slightly rubbing my KYB adjustable shocks, but no harm done. I am using the Cobra MC with the stock booster, I didn't want the brakes to be too touchy...

One thing I must ask, bigvino, are the rear brakes drum or disc and are you getting the rear axles with this kit? If so, what car were they on? Hopefully it was a Fox.

The issue is, a Fox rear end will work with the Ranger axles and drum brakes or using SN95 disc brakes and a modified caliper bracket. 94-98 SN95 axles will work with the stock disc brakes and will work with the 17x8 stock Mustang wheels you pictured. 99-04 axles will not work with a Fox rear end.

Good luck on it! I did mine like 8 years ago, and it was my first real mod to my car. Well worth it IMO!

Oh, and it is not an extender, it is an adapter to fit the passenger line to the Fox hard line, a Weatherhead 7828 fitting I believe. http://www.imperialsupplies.com/items.asp?item=0901640 Make sure the bleed screws point up on the calipers, I've had people put the calipers on the wrong sides before and swear they needed the adapter on the driver's side!

The rear drums are included with the kit and they came off a 91 LX. but i dont think the Rear Axels are from a 99-04 model though.. its just the spindles are from a '01...ive heard that the 01 spindles stick out about 8mm..compared to the SN95.... but ill hold on to the 01 front spindles till they become a eye sore..
