cad caps on my 51 chevy

so i have a set of 53 cadillac caps but they don't fit over the spindol bolt in the front so what should I do ? i heard rally style beauty rings might work. and I also heard of reversing the rims but where can i get that done or get some or if that changes the turning radious??? so many questions sorry just wanting to find a way

check with wheel vendors here to reverse rims, or maybe can set you up wit rims that will work with caps
