Most rear disc kits have a requirement for a particular flange and center register diameter. Will depend on the kit. Read the install instructions prior to purchase. For example, the Right Stuff Kit I just used on a non-C-clip BOP 10 bolt uses a axle flange diameter of 6 3/8 and a rotor center of 2.915 for the hole.

My axle flange pattern for the A body is a 3.375 center to center top bolts, and I don't see it listed on the Wilwood site. Yours should be a 3.125 on your 'bird, and I don't see that one listed on Wilwood either. I think their' chart may be off, might want to call them. Pretty sure they have rear kits for 10 bolts.

HWYSTR455,
That's correct, my rear axle housing flange measures 3.125" and it's not shown on Wilwood website. I had already spoken to them twice (hope their products are better than their customer service/tech reps) and after each call I didn't feel confident with the accuracy of the information they provided. I trust and rely on the memebers here to help guide me.

Anyone install a Wilwood rear brake system on a late 2nd gen coporate 10 bolt?

thx.

You called Wilwood and they couldn't tell you if they had a caliper bracket for a 3.125 10-bolt?

Call and ask for post-sales tech, tell them you have the kit for the 3.500 axle, and ask why it doesn't fit. They may be able to give you a better answer!
