1970 duster marker lights

Toqwik said
My 70 duster is missing both front fender marker light lenses. It appears that they just snap in there. Is that correct? If so where is the cheapest place to buy replacements?

These are what you need.

They are snap/in like you said, they are also adhesive backed to help keep them in place.
