There's a great video clip that turned up, interviewing an original purchaser of a 427 Cobra who talked about how they got aluminum wheels because there was a problem with the magnesium Sunbursts exploding when they rubbed a curb and 'sparked.'

Ed Leslie told me that they dropped the mag wheels because Ford was pushing Shelby to improve the profitability of the 427 Cobra. They brought in the aluminum wheels along with the 428 engines. I can attest to the sparking effect because I spun out in the Yosemite tunnel in 1966 rubbing the very high curb with my left rear, it looked like a 4th of July celebration, it bent the mag wheel but it did not break. I did not know that Sunbursts were ever made in magnesium.
