On my 94 dually 4x4, the previous owner installed a solid front bumper, (the diesels originally have bumpers with the two holes on them right?) is this a bad thing for cooling perposes? If it is, I was planning on cutting them out instead of buying a new bumper to save money, it's also painted to match truck. If I'm gonna have to cut, can someone give me rough dimensions of their size and location of the holes... Thanks
