For the 1970's it's easy. ALL SS cars got CLEAR lenses with a amber bulb inside.

ALL NON-SS cars got amber lenses.

Your in luck if you've got a genuine SS, the clear lenses are plentiful.

Being a '70 Malibu owner, I know from experience that the amber lenses are hard to come by unfortunately.

Kevin-

No need to swap unless you want to. The clear lenses are available from just about every supplier for Chevelle parts.

The problem is with the amber ones. No one makes a repro. I had to buy used!
