Going to swap a 7.5 rear in my 88 hatchback to an 8.8. Here's my question,will i need to change the driveshaft or can I use the same one ?

Unless you have a car that was, or is a 4 cylinder engine Mustang, you already have an 8.8 rear end. The 87 and later 5.0 engine Mustangs came with an 8.8 Track-Loc rear axle as standard equipment.

Car was a 4 cyl.Now is a 351 Windsor.

Are the rear drum brakes on an 8.8 rear the same as a 7.5 rear ? The reason I'm asking is I have a 7.5 with good brakes and an 8.8 I'm going to swap in that needs all the brake parts.

Ahem,....it's not a "posi".

Posi is a GM term for a locking differential.

People that own Fords have Traction Lock diffs. (T lock for short).

Just FYI.

Yes, they are the same.

Know what else?,.....both of your threads are the same,.........Now.

Thank you for the correction, it's my first Mustang.

Couldn't find my original post,thats why I started a new one. My bad.

Brakes, and axle shafts are the same between the 7.5" and 8.8

 

[Ghostrider59]

Thanks, I'll swap everything from the 7.5 to the 8.8.

I am also getting ready to do this swap on a '84 that I recently picked up.
Let me know how it goes.
From what I've read this is also the best time to upgrade your control arms and replace the spring isolators.

 

[Ghostrider59]

That's what I plan on too.May as well while it's out.I'll keep you posted on how it goes.
