On my 91 I got tired of trying to get some header exstions to work around the factory cross member. After some research I found put the holley black hart crossmember would work on my dakota. I just had to redrill two frame mount holes on the holley crossmember on the drivers side. The holley black hart crossmber was designed to install a gen3 hemi in a 87-96 dakota. It even has different mounting plates for different model transmissions. Here is some pics of it installed on my dakota
