I'm building a 89 lx,  

In the one piece headlights can you do HIDs in them yet? Last time i looked i couldn't find a pair you could.  

Can you run HID in these Part number:LRS-13008CDHB-K  Or would i have to use Part number  LRS-13007CDB for HID?

Anyone care to shed some light on the matter? I'd REALLY like to go to a one piece headlight design.  

We don't have it set up in our system yet, but I sent a link to our research department so we should have it ready by the end of the day.

 I'll post a link once it's ready.

Jonathan in the research department got back with me and said that he can't find an HID kit for the 9004 bulbs from our suppliers.

I had just stumbled upon this company that makes HID kits for 87-04 mustangs. Here is the link:
