i found a ford 9in cheap but its out of 3rd gen will it fit n my 4th gen im not sure if it will fit rite n or not let me know thanks for ne help

 

Should be a direct bolt in, but its going to be at least 3" narrower than the 4th Gen rear axle assembly (some say the difference is 4"). You would need to run wheels with near "0" offset, compared to the stock 4th Gen 50-55mm offset wheels.

 

I'm not a big fan of them personally but you could also get some bolt-on spacers to set the wheels back out where they are supposed to be if you didn't want to go the route of getting new wheels.

I know a lot of people run them and have no problems, but to me its just one more thing you are putting in the mix that has a potential to give you problems...

What is 'cheap' if you don't mind me asking?

 

700.00 minus brakes and torque arm bracket

 

thanks for the info greatly appreciated

 

You should be able to get a bracket pretty easily for the brakes and run the stock brakes- The torque arm bracket will be a little harder to get, but a call to Moser or Strange and hopefully they can get you what you need.
