Center Caps on 17" Steelies

I tried the Charger aluminum wheels on my Cuda and ending up bending 2 studs in my new axles (just borrowed the rims). Then when I went to put the 4.5 BC rims back on and it looked like the studs were cracking where the thread was cut into the stud close to the hub. Now with the steel rims it may not force the stud over as much, but either way I would be careful!
