I know this question has been asked before, but i cant find the thread to reference;

i have 87 4x4 fenders, bumper, and i think a valance...on a two wheel grille. Im having issues fitting the bumper properly on my 2wd bumper brackets, do i need to get the 4wd brackets? also, does anyone have pics of a 4wd valance (84-88) ?

 

I think you will need some combo brackets from what all I have read. Check out Custom Auto Parts, Airbag Suspensions, Rollpans, Bumpers - Street Metal

 

I have 4x4 fenders & a 92-95 4x4 front bumper & valance .
Made my own side brackets. & the main mounting brackets are from FBI (no longer around) Street Sheet Metal is the off shoot !
I had to modify the main brackets,easily done!
