Grill guard 3rd gen to 2

Would I be able to install a western brush guard on my 2015 Tacoma I see a good deal on marketplace but the grill guard says it only fits a 2014 through 2019 Toyota forerunner could I modify it to fit the truck

 

I have a 2015 2 gen

 

Anything is possible with a welder, a grinder and some paint. "A grinder and paint make me the welder I ain't"

 

You want to put a grille guard from a 5th gen 4Runner onto your 2nd gen Tacoma?

This I'd love to see.

 

This is the front end the grille guard you want, was designed to fit:

Front end conversions, yeah. I ❤ that 4R front end and would do that to my Taco if I had the time & money.

But OP is just asking about modifying a facelifted 5th gen 4R grille guard, not the whole kit and kaboodle.
