I need install a set of Mazda 3 turn signals on a stock 2017 Mazda 3 Sedan.
I thought I could in from underneath - but I cant do to the long plastic underneath.
I guess I need to drop the front body parts to mount them to the backside of the front fender?

.. its weird that I cant install from outside and slide them inside to the front bumper.

there are 3 pieces total I actually need installing, I have them all... just need some guidance on how?

Do I need to drop the entire front body parts from the hood down - the grill - everything? .. or can the Front fender be clipped / pulled off?
I'm not sure how its all connected other than the top screws from under the hood.

Any help - YT videos - etc.
Thanks in advance.
