Depends on exactly what you're wanting to do. If you just want to run the 03-06 hood with the screened in headlight hole, for a race look, mounting the hood is pretty easy. If you want to run the 03-06 headlight, it gets a lot more involved. The brackets for the headlight have to be precisely in the right place. Here's how I did it. I found someone with a bent 03-06 frame and bought the front frame section. I then carefully ground away the welds till I had just the headlight and hood brackets. Then I made a jig off my 05 frame. I then used the jig to locate the brackets on my 88 frame and welded them on.
