wider steel wheels

I had two 14"x5 1/2" Magnum 500s made into 15"x8" for the back of a Coronet that i had.
I don't recall the name of the place but it was in Oklahoma. The was another that widened two plain black rims for me also -this is all going back 15 years or so ago.I saw the ad in Mopar Action magazine and called the place up,told them what I had.They gave me a quote ,I sent them the wheels and about two weeks later walla! They were exactly the way I wanted. The wheel centers on many steel wheels are the same but the outer "barrel" is either 14"/15". Just make absolutely sure of your measurements!!!! Wish I could remember the companies names........Dang old age and too many beers as a young man...........
