THANKS FOR THE HELP

i ment 03 gt!

fit yes but it's a 7.5" not a 8.8" and it's a peg-leg and it's not the right thing to do.

find a 99-04 GT axle and save yourself the hassles.

FWIW, you can also use a 94-98 GT axle BUT you should use 1" wheel spacers in the back to bring the wheels back to where they belong.

What R3d said or if you got the cash, a 9" rear is always good, especially if you have big plans in the future.

what would(and i mean what ford vehicle)have a 9" that would just bolt right up or with just a little fab, ya kno with out having to get longer/shorter axles

bassman97 10-27-2008 06:55 AM

None, that's why I said if you have the cash since a custom housing from places like Currie would be needed.

i thought that the 94-98 and 99-04 rear ends where the same length, and that it was the fox bodys that had the slightly smaller one. actually, i'm POSITIVE that the foxes had one that was 3/4" shorter on each side as compared to the sn95's.

Are you only looking for the axle or are you looking for a whole new rear end?

segir 10-29-2008 04:09 AM

just the axle.

bassman97 10-29-2008 04:58 AM

Nope, R3d is right. 79-93 were one size, 94-98 were marginally longer, 99-04 were a good bit longer, and now the 05+ are also longer.

engineman312 10-29-2008 05:00 AM

if your gonna get new axles, i'd get the aluminum ones...

bassman97 10-29-2008 06:45 AM

No such thing as Aluminum axles. All axles are steel and it would be bad news if a car used Aluminum.

What is the stock 2003 mustang gt rear axle passanger size? in other words what do i need to buy to get my stang back to the way it was when i bought it.

r3dn3ck 10-31-2008 07:56 AM

if you need a stock 03 AXLE shaft, just the shaft, no housing or differential or any of that jazz then you can use one from any 99-04 mustang gt or any of the post 99 mach1's.

Either of the sets below will make you a happy camper and they're not expensive or difficult to install.

my bad. i thought the aftermarket ones were made of aluminum. must have been thinking of the driveshaft.

jjtgiants 10-31-2008 03:50 PM

I could be way off here, but will a ford explorer axle work?

segir 10-31-2008 06:21 PM

problem solved fellas. well i just bought the axle off ford it was not expensive at all. it was a 8.8 31 spline 5 lug axle..thanks for the help.

such as a whipple s/c ?

r3dn3ck 11-04-2008 07:37 AM

that would qualify as big plans yeah. A 9" is bullet proof but since it's a different housing setup than stock it limits your available suspension choices to fairly stock layouts. Sure you can use all the same control arms that any 8.8" car (with something like a Currie bolt in 9") but you can't use off the shelf tq arms or watts links. Usually that doesn't matter to guys with designs on a blower.

You can build an 8.8" to be pretty tough but it'll never be a 9".

bassman97 11-04-2008 09:10 AM

Watts links should be fine since the ones I've seen either attaches to the shock mounts (which should be the same as in a 8.8) or the axle tubes (which slight modifications to the Watts link wouldn't be a big deal). But yes, you can't use a torque arm but you can still use the Evolution Motorsports Tri-Link, so all is not lost. Probably the biggest mistake Ford has ever made, by replacing the 9" w/ the 8.8".

r3dn3ck 11-04-2008 09:51 AM

too true. imagine all the warranty issues they'd have gotten out of if they just used the 9"

bassman97 11-04-2008 10:56 AM

Or the money made by GM guys buying 9" rears from the dealerships or though FRPP.
