When you remove the tow hooks and brackets you will not be able to reinstall the swing arm as they are part of it. I went out and bought stainless steel hooks with 18,000lbs pull strength and made a license plate bracket out of 1/4 alu. The bracket can get mounted behind one of your tow hooks if you do it right.
if you just want to buy a kit
