hey question, first time posting here

okay so I'm planning on buying new headlights, so I decided to mess around with my current headlights by following the gunmetal spray paint DIY you guys have...

well I didn't use gunmetal but my paint didn't come out as well as I had hoped, it left a few streaks and some dark spots, etc....

anyway, so my question is, instead of buying new headlights, is there any way to just buy the various parts??? meaning can I buy and replace just the clear lens, or maybe buy and replace just the chrome reflector sheet on the inside of the headlight??

the reason I ask is because now I'm kind of interested in having something other then the standard black/chrome/titanium/gunmetal colors, and I would like to experiment but not by buying different headlights every time for around a 100 bucks a pop!!!

If you know where I can get brand new clear lens/chrome plating that would be fantastic... otherwise I'll just buy a new set of headlights to use and keep repainting over my old set I have until I get them perfected... problem is the inside reflector is cracked and I need it replaced :\
