Cobra Caliper and 5-Lug Fox Axles

[TenorPlayinGuy]

I had done my rear 5-lug swap when I upgraded my rear with 3:73's and Eaton diff. Using replacement 31-spline stock width axles and north race cars brackets for using the cobra caliper and rotor. I notice that the center hub is smaller and the rotor doesn't really sit solidly in place when I go to bolton the wheels. Is there any sort of hub specific axle I can get? or any special machined ring I can use for this? I just hate to imaging my vibration at 65mph is from this.

( i know the vibe can also be from the driveshaft, clutch, flywheel... I'm working on it)

Thanks in advance fellas.

This is on my 87'

I'm in the middle of gathering all the parts for my cobra brake swap and I'm actually "stuck" on this issue as well. North Race Cars sells a stock style fox axle with a SN95 Style hub to address this issue. I have an Auburn 31 spline Differential, which I don't want to swap out, but is not compatible with the aforementioned North Race Fox Axles. The only solution I'm aware of (and I'm by no means a brake swap expert) is to run the appropriate spline configuration SN95 length axles with the correct hub. (I hope that response makes sense, in my head it does... LOL ) Nevertheless, I'm interested to see what others have to say.

diskbrakesrus.com sells a machnined spacer.

IIRC it's 2.75" OD, 2.5" ID and 1/4" thick.

That link sends me to a page that seems the host is no longer available, or perhaps its the wrong page.

Yep! It's discbrakesrus

Thanks! I'll have to find it!

MAN! You're a LIFESAVER!!! I didn't want to have to replace my 31spline axles.

This will be perfect as I'm just about to get a new set of the PowerSlot rotors with that anti-rust finish. And these are only about $40 shipped! Phew!
