Smog and a/c removal


I removed my smog pump and air conditioning system. Now I have the brackets that look so ugly. What are my options to remove them? Do they sell kits to replace and make it look a lot cleaner?

thank you!!! All that other stuff looks so unnecessary. I don't understand why they just can't make a tensioner without those useless pulleys and use just alternator, power steering, water pump and main.
