How hard would it be to add my own 500 Series light head to make a Inner edge? The reason I ask is cause I am thinking of making one with me Liberty heads. I want to do it this way so that if I choose to go back to my liberty I can. I also need to know if anyone can get what I need to do it. Please let me know. If I cant find the parts I am going to make my own and I would like to know what I could use. Thanks for the help guys.
