Hey guys,

I just recently bought an '81 Mustang LX 5.0 and I was concidering changing the rear-end. I've found a Ford 9 Inch that a friend has that seems to be in good shape. How difficult would it be to swap the rear ends out in respect to length and brakes and such. Im not sure what the 9 inch came out of, but I believe its a large 5 lug. This is kinda my first project car and im a bit new to this. Any help would be much appreciated

You probably will have to shorten the 9 inch if it was out of a truck. I'm not sure who sells them but somebody on this site knows who sells kits where you can shorten your own rear ends as long as you have a method of cutting and welding. You'll have to get custom axle shafts made too, I got some from Moser for $400 for my 9. I'm pretty sure you can't use the brakes from the 8.8 on the 9, but you can use the brakes from an 8-inch which are pretty plentiful in junkyards as long as you are willing to settle for drums. You will also need to change the housing to accept the 4 link suspension found on mustangs as well as get a custom driveshaft. <a href="http://www.currieenterprises.com" target="_blank">www.currieenterprises.com</a> sells custom 9-inch housing to put into fox-body mustangs. Probably will cost you around 300 just for the housing. All in all, I think its a good investment.

Hey, thanks for the reply. Is Moser a person? or a company? haha

Also if anyone knows the site that has the shortening kit please post it or pm me.

Thank

Hi all,

I'm new to this board. I have a 1968 chevy C-10 that I'm building.
I have a question about the rear change. I have read several articles about different ones to use.
I am totally confused....I would like to use a 9" and have the disc brakes. I have read that you can use the (Ford Explore 88-89) and have the disc brakes, but it seems difficult to shorten. So,
I'm open to suggestions as to what works well or any ideas.

Thank you,
Merl
