In the mid to late 80's when Ford was phasing out the 390 I had the pleasure of some warranty engine jobs on Ford trucks. I received as new parts from the parts department short blocks with oversized cylinders, reground crankshafts and a host of other rebuilt/remanufactured parts.

One of the many reasons Ford products can be 'interesting' to work with.

How well I know about design and trade secrets. We built heavy duty gas turbines. Several folks that I worked alongside, including the bosses boss were caught doing that. Some were walked out the door of infamy never to be seen again, some went to jail. All of my travel records were subpoenaed along with correspondence and my files. Then being investigated by the FBI plus the fact they questioned many of my international contacts - was not a career path aid.

bentwings It's possible you have a truck housing. Mine has 3 1/4 in dia tubes. Also a strange "stick out". I don't remember the numbers but they did not match anything in the catalogs. I also have the stock roller bearings. While a PIA they do last longer than the ball bearings.....The seals leak bad so use lots of silicone. Several cruise buddies have the ball bearings and have continuous problems with them especially with deep offset wheels.

I used a Speedway weld on bracket kit and those goofy Seville E-brake calipers.

If you wind up using these you must use a 10 psi residual valve. This is noted in a GM TSB somewhere. This is the only disc brake that needs this. It helps control the piston retraction and thus the pedal travel.

Glad that you pointed that out. Many folks aren't aware of that

There is also one more 'caveat' to consider and that's the amount of axle projection outside of the housing which also determines the bracket design. I found that even a couple of aftermarket suppliers had no clue, ECI, being one that blew me off when I talked to them about my '57 small bearing housing but Wilwood knew what to do

Another consideration to the three Ford bearings/axle housing ends is that usually(not always) an aftermarket housing is built with the 'big'/late model Torino version.

LATECH Sure sounds like the wrong caliper mount to me.
Who built your rear?
Or could the rotors be too small diameter?
I would contact the builder see what he says.

I'm probably not the best person for this question so hopefully someone will chine in here.

In my thinking if you get gm brackets they wont fit the ford axle. And if you get ford brackets they wont fit the gm calipers. If there a bracket that puts the gm caliper on the ford axle? Wait for someone else to answer, this isnt my forte.

9" rear disc brakes problems

Guys, I had a 9" fabbed for my 1966 Chevelle..it has 5 X 4.75 wheel studs for the GM pattern. I bought the SSBC rear disc kit, and installed it. The disc brake caliper mounting bracket was very hard to get on...holes didn't align and had to be drilled out to fit. NOW, I have the problem where the pads are only contacting the outer half inch of the rotors, and I have a very hard brake pedal, even with four-wheel power discs. SSBC has offered no help. Do I have a wrong bracket for the rear end issue or what? Any advice is greatly appreciated, as I have no experience with 9' rears at all.
