I use them even with factory swaps. I have 95 cobra brakes on both my foxes and still used the aftermarket ones. A wilwood on my race car and a summit on my street car. Its cheaper this route and you can adjust for your driving style, i like a little more rear bias, especially if towing.

I'd see that as a downgrade with the diff. Same with the axle in the crown vic i'd want new seals and stuff so i'd prefer the explorer route. Its another good option though, would be worth looking into if the axles are the same length, my worry would be the axle mounted ABS sensors and losing the RABS setup in the truck Might cause it to act weird.

I'm pretty sure it's a smaller flange bolt pattern on the mustang then needed. They are smaller rotors as well.

Ummm....How is that a downgrade? Same 8.8" setup, etc....Just with the 28 spline setup.....
As far as that goes....You could strip the differential and axles out, and use the trucks'....If the axle tubes were the correct length....Might even be a tad wider....Given the fact that the car has a wider track, than the trucks..
Otherwise...You've gotten a 8.8" setup, with factory rear disks....Again....just another viable option...Seeing as Explorers are a touch rarer than CV's...

But to put it somply, yes 31-28 is a down grade

The cobra stuff is 11.65" might be enough, but then rest would take some figuring.

Two things break axles, weight and torque, both of which the truck has. I know i personally dont want to go to a 28sp axle when I already have the stuff from the explorer and can keep the stronger 31sp stuff. Especially when I have a pretty stout 306 going in.

That was just one of my first thoughts about the CV axle. Still seems the cheapest route is the explorer stuff. But if the CV worked it would be a quick solution if someone didnt mind about the spline issue

Funny, cause around here there are alot of explorers, and people are more concerned with robbing the GT40 stuff then the brakes, good luck finding a CV or a truck at the yard here. Which sucks cause i'd like to get the axles and have a spare set to mill before doing the swap

And there's 3 body shops that double as a yard for nothing BUT CV's....
So a CV, or parts is no biggie....

Yards around here are starting to dwindle with domestic stuff anyhow. I remember when I could go and scope out 50-60 foxes, good luck finding anything ford now. But the exploders are everywhere

I wouldn't bother swapping the entire rear axle for a CV axle. He has a perfectly fine axle under his truck, and he's already made it clear about 8 posts up he just wants to swpa the brakes. If it were me, i'd nab a Vic axle OR a Explorer axle, whichever is cheaper and easier to find, take the brake setup and bolt it onto his axle he has, and redrill the rotors to the 5x5.5 bolt pattern. You guys are overcomplicating things. Swapping in the Vic axle would require adding leaf spring perches and shock mounts, and the Explorer rear axle is too dang narrow.
