As Iīve said, I have a -72 El Camino.
The two things I donīt like about it are the grille (sorted, thanks) and the tail lights.
Now, what are my possibilities?
(And I hope you donīt take as a "rapist" thinking about this.)
There is a LOT of different kinds of tail lights out there, I know. But what will fit to look good, thatīs the problem. As we all know, it should look like itīs meant to be, not like something "hey, look thereīs Beetle lights on El Camino!" (baaaaaad example).

I want to go toward lowrider / ledsled theme, you know. Really low, shaved door handles and emblems, fender skirts, tail dragging etc.

Any pointers?

Nothing will be a direct bolt in swap, you will need some metal fab and welding.
Everyone uses them but caddy taillights are popular, dont know the exact year am guessing 1980 and up.
Ive always loved the look of 1950 Pontiac taillights but dont think they would look so hot in a 70ish el camino.
