Looks to me like you could get away with cutting out a small portion which may be enough to gain some clearance...Even a small amount cut out would yield a good amount of additional clearance. You can weld cast all day, as long as you have the heat up...and the best thing to do would be to cut it and then with the piece off the vehicle, make the joint between the two "V" shaped and fill it with weld. A few passes would most likely do. If they can weld two pieces of 1" thick plate together, you can most likely weld this skinny piece together.
