Road Runner Nest

A month ago I purchased a pair of NOS Mopar fender mounted turn signals. These are for my 1974 Roadrunner. I'm wondering where exactly these go on the fender and how they attach. I've been told to see an actually car with these on, and I'll do that, when I come across one. I'm just wondering if anybody else knew.

Thanks,
Adam

For the turn signals there are usually factory prefabricated holes for them.
if not you wil lhave to measure and fabricate the holes your self and then connect the wiring and gasket and ground screw
