SB brackets were specially designed for the Westin light bar but are much stronger than I anticipated as I have ‘bumped’ a few vehicles at 10—15mph and they held, protecting the front of my VX. But, even if you found a bar that measured the same, the brackets are not strong enough to back up a true push bar.
I can have brackets made for anything but need to know what existing bar fits the contours of the VX - my supplier here does not keep enough bars in stock that I can hold up and test so if someone in a larger market could do that, I could have the brackets built. This of course would not be strong enough to support a winch as that needs supports through the bumper cover and is best done custom, on the vehicle.
