Ok if you look at the picture the measurements are as follows- in between space from one inside to the other is 36", now the outside measures 42' & 48".. That's outside to outside.
I just thought I'd say that if you or someone you know can weld, you can make new or additional brackets to fit any vehicle. I bought a brush guard that came off a 2003 Ford F150 and made it fit a 1992 GMC S15 Jimmy. Just a little work and it can fit just about anything.
