You're actually looking!!!! What would your wife think? J/k.

Anyway, I saw a post the other day about getting great stuff off of craigslist. So I took a look and found an 8.8 Mustang rear end. I couldn't pass it up. I got it for free. They guy wanted it out of his garage to make room for other projects. He told me that it was out of a '90 5.0 Mustang. I'm planning on cleaning it up and painting it. I'm not anywhere near purchasing the kit, yet. But I can still collect parts, right? :D



The drum brakes on this side are gone. That doesn't matter much becuase I plan on changing it to disk. I'm still not sure if I want to do the 5 lug conversion.




The pumpkin looks like it's in good shape.


Here's the tag. It says S2L73. Reading from other posts, I believe that this is a 2.73 ratio and the L stands for Locker. Is that right? It's a pretty low ratio. But I plan on using it as a daily driver. Are there any issues with a 2.73 as a round the town, get me to work type car?


Other questions that I have:
Do I need the arms on top?
The brake lines are still in good shape. Do I need them?
Any suggestions for prep or paint?

Yes, you have 2.73 gears.
You need the upper arms if using 4 link. 3 link does not use them.

Most guys here will say switch to 3.55 rear gears.

5 lug conversion is a good investment.

Use POR 15 for paint, requires minimal prep work.

If you've seen one rear end you've seen them all. Do a search on the subject and you will see a lot of the brackets can be just cut off. A sawsall (metal blade) will come in handy. You will not need the weight under the front, just lay it aside. I got a wire brush for my grinder and went over mine then primed it and put a good coat of paint on it. Good luck!

I second the 5 lug conversion,you'll have a better selection of wheels to choose from.

Check for straightness to be sure it was never damaged. Not sure but what year did 5 lug take over? Thinking it was 95? Hopefully someone can chime in here since having 4 lugs would make yours a fox rear. Measure the width,post here so we can tell for sure the year. I used a portable sand blaster to take heavy stuff off with power tools and wire brushes for the tight spots. Rust converter followed by some epoxy paint spray bombs finished it off like new. Keep the top arms if going 4 link,if not remove them.
For brake lines I bought new lengths from parts store and duplicated the originals. Nice find.
Gears? Depends on engine set up. Stock can do fine with those gears. most upgrade to a little higher ratio depending on performance wanted.

You are correct, 2.73 gears. That is the stock manual trans rearend. They would work fine for cruising. Alot of people go to lower ratios like 3.27,3.55 or 3.73. The lower gears do make first gear very low. If you are going to have a four link suspension you will need the upper control arms. If you switch to disk brakes you will need new brake lines but, save the old ones to use a a pattern to bend the new ones. I sand blasted mine and then painted with POR-15. You could clean it with a wire wheel.

Free!!! No better deal, other than if he paid you to carry it away.
You need the upper arms, lowers too!
Unless you plan on buying new tubular arms for the 4-link, or go the 3-link route.

Here is something I learned about new rear lower arms. Don't buy weight jacker style adjustable lower arms. You don't need them , because an adjustable spring perch comes with the kit.

THAT, PLUS, the adjustment screw /bolt will ride way to low with the traction-lock lower bracket FFR supplies with the kit.

New brake lines are cheap.

Axle length may or may not matter to you, as new 5 lug axles are available "Fox" length, SN95, or '99-'04. They grew in length with each change. Axle length comes into play when chosing what year the disc brake kit comes from and the tire and wheel size and offset package you chose.

General rule of thumb, shorter axles give most room for tires.
I've found that the most affordable used disc kits require the SN95 axle length. Wheels seem cheaper for them too.
Confused yet?

Since you haven't ordered yet you've got plenty of time to scout around for inexpensive 5 lug replacement axles. This is a perfect opportunity to thorougly recondition and upgrade that rear end without overspending for parts and labor to hurry up and get it done.

Passenger side Ford Airostar or drivers side Ranger axles are five lug and are a direct replacement for the Mustang axles. I used a mounting bracket from Richard Oben and '94 Mustang calipers and rotors to switch to disks.

You should spend some time designing the car that you want. Once that is firmed up, then you will know what you want to do with the parts that you acquire.

For instance the 3 link is a $500 to $1000 item. If you go with a 4 link coil over rear end you are then into it $500 then you are only $500 away from a 3 link. Take your choice and pay your money.

Thanks guys for the information. I am going with the 3-link setup. I've already decided that. It sound's like the 5 lug conversion is the way to go. I'll look around to see if I can find some in a junk yard. I might look into buying a 3.27 or 3.55 set too. I'm just trying to save
as much as I can. I know, I know. The forum is like the Borg, it's futile to resist.

Herb: er.... thanks for the compliment, I think. ;)

Ken: It was aready empty. I'll have to fill it up again when I start cleaning the thing.


You guys are great. I love all the info that is provided. Thanks.

Since you are going with the three link, you can just hack the end brackets off. however, keep the center ear holes incase you decide to add that extra bracket. You will need to run new brake lines and you will also need a pair of fortes offet caliper brackets. look for some antimoan brackets on ebay-they are really expensive from the vendors.

I bought a '94 diff. It is already 5-lug/disc. It's not much wider than Fox either. To me it's worth starting with this because axles and disc conversion can add up the cost of buying the diff.

LMAO...

Saturn, you're off to a good start.

Take a look at my rear...


I ran the flexes right off the chassis. A lot simpler.


congrats!!!
