Thats a bit tough to quantify...
After making a wooden template to make sure I could properly modified it...
....I purchased a stock Toyota rock bumper.
Then got a used WAAG brush guard from e-Bay that I chopped down....
...and welded to the top for light guards .
Lots of time..cutting..bending...and my crappy spot welding.
Fab up entire new bracket set up.....
....then prof welding to complete.
To do it now..it would be about $1500....just for parts..not incl labor.
Quotes I got to have one similar made ranged from $1850 - $2400
You need to post some pics of your rig
