This is how I made mine.I had 4 15x6 bbp and 4 14x? sbp ralley's so I mated them.But I have a plasma,mig,tire changer,balancer,press and sand blaster(not bragging, it's how I make my living).So all it really took was my time,labor of love they say.I priced them out and say $100.00 each, shipping to N.S. and all the BS at the border they would have been pretty expensive,so I decided to try it.Read it in an old Mopar Mag.
