Here are some close-up photos of the L Brackets.
Here is a close-up of the front mount - You also have to put a spacer on the front bolt of the Passenger Peg Mount, but if you are using a high mount can and no pegs, this wouldn't be necessary...
Here is a close-up of the rear mount - It actually is connected to a piece of tubing that inserts into the end of the subframe and hangs out in between the bodywork and the undertray...
As you can see, it doesn't take up much room so I don't think it will interfere with a high mount can, but that's just based on my opinion, not actual experience. Make your own judgement as I'm not making any guarantees...
Hope this helps...
