I have those & they fit OK but tight with 0.89" bars. If you're just driving on the street the 0.89" ones are very firm, I wouldn't want to go any bigger, smaller would be OK. I also have stock mounts but use a torque strap. The Doug's are not super-difficult to install but the bars do have to come out as a minimum. I cheated and put them in with the A-frame out so it was very easy that way.
