hey, I have a 1999 f450 dump truck and I wanted to get rid of the old yellowed headlights. I have the single 9007 headlight bulb and was wondering if anyone knew if you could put the dual headlight bulb lenses in place of the single. Not sure if they are the same size or not. I know the wiring needs to be changed to fit 2 lights instead of one. But are the lenses the same size? any info? I can't find many single bulb lenses around. I was hoping to find a single bulb projector lens setup but will take a dual bulb if that's all I can get. thx, Andy
