Center Caps on 17" Steelies

i wanted those for my ride as well, just to have something different..................but the pattern is different, 5 x 4.5 is 5 x 114.3mm (if memory serves me correct) , but the 300c and magnum are 5 x 115 mm........
you can physically put them on, but they are not correct.........i was told there are major risks of vibration and failure, I want to be wrong, cause i want them too :cry::cry::cry:
