Does anyone know for sure that Chevrolet offered a 15X7 SS Magnum Style wheel optionfor 1970 El Caminos & Chevelles? I've read about ther availability in several articles and ads...but all the factory data only shows 14X7s available for SS cars in '70.

The only way they came was with a 14x7. Some other GM vehicles came with a 15x7 magnum style rim, however, this was chrome.
