what rotar will fit disk brakes for a 1978 model ford 9 inch 4x4. parts house has no clue.all that we have tried lug holes are to big.

 

Say what?

Are you trying to do a disk brake swap? If you are you need to start with 78-79 F150 front rotors or Jeep CJ 70s-80s Front rotors.

we are putting front and back end from 78 on a 95 cj7.we have one rotar can not match it up.

 

The front axle will be a Dana 44, not a Ford 9-inch. The rear axle is a 9-inch and should have drum brakes.

 

back end has disk brakes.

 

If you are using a Ford front axle and a Ford 9 inch rear end and want to convert to rear disk brakes you will use 78-79 F150 front rotors.

The axle flange will need to be turned down in order for the rotors to fit over them.

For calipers and caliper brackets source some Chevy 1/2 ton or Blazer parts.

I'm assuming a few different scenarios:

1) Truck has had disc brake conversion done to rear

2) Truck has passenger car disc brake 9 inch with 5-4.5 or 5-5 bolt pattern

3) Truck has later disc brake 8.8 with metric bolt pattern
