You have brackets with bolts and can use bushings to get the right spacing. Couple of thread inserts with rod ends in the front of the lower wheelie bar assembly attached to the brackets. Distance from the axle centerline looks OK.
You can move the shocks out some if you want or leave them. Put a couple of brackets on the top of the housing brace inboard of the shocks. Use a double bracket so you can use rod ends in double shear and don't get the rod end centerline too high above the axle centerline. LH thread rod ends in one end of the top bars for height adjustment without disassembling the bars. Run the top bars from the wheelhouse up to the brackets.
Top bars don't have to be parallel with the bottoms. In fact, I prefer them to be non-parallel to give the bars some side to side stability. Cant the top brackets out accordingly. Spherical rod ends will tolerate some misalignment but make the effort to keep everything in line.
I prefer to use rod ends at all attachment points rather than a clevis on a single tab.
