A 1974 Duster - My 2nd one, 41 years later!
The smaller L pieces fit in the OEM bumper shock hole. The other pieces that bolt to the bumper was welded while it was attached to the bumper so it would follow the lines of the bumper. Everything is slotted for adjustment in all directions, in...out, Up...Down and side to side.
