I have been looking at lot of post on here about brush guards and i have looked at all the links but i still have a question. Will a brush guard for 97 blazer fit a 2000 model i cant seem to find one that says it fits a 2000 for as cheap as the ones that fit the 97

 

If it's a frame mounted one you shouldn't have an issue. They are the same frames. The only issue you might have is the shaping and clearing your front bumper. If that is the case you could make it fit with trimming.

 

I thought that most of the just mounted to the hooks in the front how do i tell if it is a fram mounted one

 

If it's mounted to the tow hooks area that's frame mounted. The tow hooks are attached to the frame. Some styles mount to the bumper and not to the frame.
