    Sorry to dig up and old thread. Is there any advantage to using the cobra bracket vs reusing the stock gt?

    The bracket that the caliper bolts to is the same as the ones on the GT and V6. The backing plate and anti-moan bracket are taller to push the caliper out farther. On my Cobra clone project, I used the V6 rear calipers and brackets (they were new and painted already) without problems.

    The rear caliper brackets ARE NOT the same for GT and Cobras as noted in the picture.

    21_cal_comparsn.jpg

    The reason I used the correct Cobra brackets are, prior to my install, research indicated some people needing to use washers to properly position the bracket over the rotor.
    Without the washers, the rotors eventually wore into the caliper bracket.

    I didn't want to mess around with washers, so I used the correct Cobra Caliper Bracket.

    My buddy DID NOT use the cobra brackets, but instead re used his gt brackets.
    While we were removing his exhaust a couple days ago, the problem is clearly visible.
    The outer edge of his rotor has worn into the upper "ear, of the GT caliper bracket.
    I'll snap a picture of it later.

    In the mean time, when you upgrade to Cobra rears, do yourself a favor and get the CORRECT Cobra Rear Caliper Brackets.

    Not sure what to tell you. While I have no photos as proof, the rear caliper brackets on the 95 Cobra donor car I had did not have the brackets you're showing for the Cobra. It had the bracket on the right. It's always possible that the calipers on the Cobra donor aren't original, but the car only had 52K miles on it. Seems kinda low to have swapped out the rear calipers. What year Cobra did you get those calipers from? Maybe the bracket is a production change Ford introduced at some point.

    The picture above is not mine.

    As for your cobra donor, perhaps the previous owner had to replace the rear caliper BRACKETS due to seized slide pins, and used whatever was on hand?

    I doubt it was a production change.

    Maybe the original owner of a cobra will chime in.

    For now, here are some part numbers for you.

    I always use a long ¼" extension whenever I remove the cross-pin bolt. This allows the use of a torque wrench to reinstall it.

    Correct me if I'm wrong, but I believe it's possible to install the cross-pin backward? The hole in the right spot, but turned 180°. A time or two in the past I've had trouble installing the cross-pin bolt after installing the pin; remove the pin and turn it 180° and it works perfectly. The most recent time I removed it (couple months ago when I replaced axle bearings on the Cobra) I maintained the same orientation as when I removed it.
