4 clock springs!?
Are you lurking eBay for cheap used ones? Thats not a cheap part buy 4 times. Even a used clockspring/SAS can work, as long as it's installed centered and hasn't been buggered up by the recycler that removed it. If you don't know where the middle is it can be touchy to find it again, I had to do that worth a Chevy avalanche the other day, it took popping the cover off to find the middle.
I don't know how you messed up your original one as it doesn't come off worth the steering wheel, but check over everything you've touched. If all else fails

Select your year, brake > brake control/ dynamic control system > vehicle stability control system > the appropriate heading for your dtc. It's a really simple circuit to test just a power, a ground and a CAN line.
