Rear disc brake coversion

So I have the tire off of my jeep right now and one of my springs broke for my drum brake. Now i have a new small parts kit that'll fix the spring but i had an idea. I have extra front yj calipers and rotors that I could use on the rear axel. Is this possible? I looked up other conversions but no one seems to have put calipers and rotors from the front of a yj to the rear. Is this possible? Bad idea? What would be required? I don't mind the work to put in to be honest because I love learning. Just curious? Thanks for advice in advance!

Never heard of anyone doing it, I feel it would be expensive to make work. Just swap a 8.8 in and call it a day...

there are 2 kits offered in Quatratrac for rear disc change over. they range from 500.00-800.00. Not sure of the quality or differences.

I don't know what Michigan inspection laws are, but I can tell you that most states with inspection laws require a mechanical parking brake to pass inspection. Doing a disc conversion from front to back is possible if you can fabricate the mount for the caliper. But it still leaves you without a proper parking brake.

I did an 8.8 conversion on mine, and instead of messing with parking brake cable conversions, I just installed a line lock (inline brake lock) on the rear brake line. They put them on wreckers and tilt beds all the time to lock the wheel for winching. Found out the hard way that the "line lock" isn't an acceptable parking brake. Even though it holds better than any parking brake ever thought of holding.
