does the track bar hang lower than the old stock one? If so I see what you mean on interferance. I have the stocker and it is close but it is above it. I had to remove the drag link from the right side (drivers) to put the cover on but that was it. after the cover is on, then you reattach the link. If the track bar ount hangs lower than stock, you might have clearance issues, I don't know...
