Thanks. I used an angle grinder to cut them off then I took my orbital sander and cleaned up the remaining weld. After that I used 320 grit on the orbital to clean up all the original brushed marks on the whole tank. I spent probably an hour polishing the tank. I would really like to center the manifold above the tank but the oval cutouts on the rear deck are to small. I might try to make a bracket so I can "pinch" the rear deck between the manifold and bracket.
