Is there anywhere to buy the brakets, lca, spring perch, torque arm, ect. To do a forg 9in swap for our cars. I have a ford 9in housing and third member to build but I don't want to drop a 1000.00 on a housing and axles. Just currious. Thanks

 

It will be easier and cheaper to buy the housing package.

The torque arm bracket can be purchased from Currie. All the other mount brackets need to be taken off a 10 bolt donor diif and welded onto the 9". Welding the 10 bolt brackets to the diff is relatively simple. Welding the mount tubes for the torque arm bracket needs good welding skills. A 220v welder is required to get good welding penetration for strength.

Is the 9" that you have the proper width? If not then it will need to be narrowed and new axles will still be required. Truck diffs are much wider than cars. You'll need to use Ford brakes and rims that have a Ford bolt pattern. If it has the 5 on 5-1/2 truck bolt pattern, you'll need truck rims or change the brakes and get the axles redrilled for the smaller 5 on 4-1/2" bolt pattern.

Buying the housing package, the axles will come with the Chev bolt pattern and the housing ends are designed to use your Chev brakes.

Without a lot of fabrication skills or required equipment to do major fabrication such as narrowing the diff, it can be a lot cheaper to just buy the aftermarket direct bolt in housing package. Use your brakes and pop in a junkyard center section. Get 31 spline axles. 28 spline are not very strong.

 

buy the housing unless you have the tools to narrow the housing and welding skills. I've narrowed alot of housings at work and trust me the tools arn't cheap. And you have to weld it just right to be strong and be straight. When i did my 9" in my car i just cut the brackets off a 10 bolt opend them up to a 3" tube and welded them on.

 

I have access to all the tool needed, I work for a large contractor that has an entire metal fab shop. I'll get aftermarket axles for sure so i can use gm wheels/brakes. Thanks for the info fellas.

 

You'll have to do a lot of fabrication to use your GM brakes on the 9" unless you buy an aftermarket housing. There are at least 3 different housing ends for the 9" and none of them will allow GM brakes to attach.

You'll need some way to attach the backing plate if using drum brakes or some way to attach the caliper mount if using disk. Since Ford axles bolt in from the outside, you can't easily adapt GM brakes to the Ford ends.

With an aftermarket housing, they use special ends that allow you to mount the GM brakes. Technically, it becomes a Ford diff with GM c-clip eliminator style axles.

New axles $345
Torque arm mount bracket $150.

You're now at half the cost of a housing package and still need to move the 10 bolt shock, spring, panhard bar etc brackets onto the 9" and fabricate a brake system. It won't take long to go over the roughly $1000 cost of a direct bolt in housing package that will use your GM brakes. If you do save any money, it won't be very much.

 

the one tool you will need to narrow it correctly is a housing alinement jig pretty much the only shops that have them are shops that narrow rears
