306craig - Obviously, your car, your rules.
But…
If it is the muscle car look you are after, then…
Ditch the idea of Mini headlights.
Take an angle grinder to the front end.
Follow
RedRatBike's different grille shape idea.
And before you know it, the front end will look like this.
Note:
I take no responsibility for all the extra work involved and the fact it may look terrible.
Jokes aside, good luck with whatever route you go down.
Cheers, Paul.
