These days, if you want a taste of the windswept convertible experience but don't want a car with a soft top, you can always look for a vehicle with a sunroof. However, it wasn't always so easy. Back in the 1960s, models with an optional sunroof were few and far between, and power-operated ones were even rarer. Chris Howder, of Lakewood, California, wanted a sunroof on his '64 Impala, so he sourced one from a Cadillac and had it retrofitted into the Chevy's roof.
