No factory alarms in 1978. That fender mount is an aftermarket unit.
Not only was this Regal SC there but George also spotted a Century TC for sale in the car corral plus there was at least 3 or 4 carb turbo Trans Ams there. I should have taken some pics. Every one was in great condition.
Hey I saw that Turbo Century pulling into a Walgreens at LPGA Blvd in Holly Hills a few weeks ago. It had out of town tags back then....350...blasphemy! :biggrin:
