I got a new sway bar from CPP, but it won't mount correctly to the front cross member of my GMC because it's different than a Chevy cross member. I need to fabricate something to carry the flat plane of the bottom of the cross member outboard a few inches. I've seen brackets made to accomplish this that are bolted on. A mechanic friend of mine has offered to weld brackets onto the crossmember, but I wonder if there is any reason not to. Will welding to the cross member cause structural or other problems?
