What would it take to do a mustang rear

**JwMonE99** · 04-17-2009, 12:06 PM

Just curious what all would it take to do a Mustang 8.8 inch rear swap?
I can get one for free, was thinking about doing a ladder bar set up?
I don't want to hear about how its going to take 2 grand blah blah and and better off getting a 9 inch or 12 bolt. I just want to know what needs to be done.
I would imagine that it would need a custom drive shaft which is not a problem for me. I currently have on the car a set of BMR lower control arms and relocation brakets? Can I re-use them?
What about shocks? are they the same?
How would rim fitment be?
If there is anything else am I missing?

Start taking stuff apart. Get a good welder and get some serious thick steel because this is going to be time intensive...

You could reuse ALL the suspension if they are adjustable. Just have to cut and weld the brackets off the stock rear end...

Watch Extreme 4x4 on Horsepower TV they do it like every other episode.. its gonna be a nightmare...

The torque arm mount would be the biggest hitch in your buggy. The mustangs and crown vics use a 4 link system. Either a mount on the diff would have to be fabricated or the car would have to be converted to a 4 link system. The spring perches, shock mounts and lower control arm mounts would have to be moved. That's if the diff was the right width.

What exactly is the 4 link system?

**thearborbarber** · 04-19-2009, 08:43 PM

A 4 link system uses 4 control arms two lower like the ones already on a f-body and two upper control arms. The uppers serve the same function as a torque arm, keeping the axle housing from rotating.

So it shouldn't be that hard. Just need to add more control arms.
There is a guy around here that can fabricate all that stuff. I just want to know how much work it would be, so when I go and talk to him he can't jew me down saying there is more that needs to be done.

Maybe like 50 hours worth of work... do you know the width of the rear end?

No not off the top of my head.

if the rear is too big or small in width you have to order custom axles and there goes the price outta the rood.

There is work to be done but it is possible. You need to make a torque arm mount, spring mounts, lower control arm mounts, shock mounts, possibly narrow it and use either different rear brakes or have different ends put on. Dont forget that the ford axles are drilled for 5x4.5 bolt pattern and you need 5x4.75. You either need to redrill or get different axles.
