Everything will pretty much bolt up as long as you put the newer fenders on too. If you try to put the new header panel on the old fenders then it's a different story.
I was ably to pretty easily modify my harness to work too. I believe the old side markers have 4 rubber prongs that go through the light then you twist to tighten, the newer lights only have 3, i just trimmed one off. And the newer front turn signals take two bulbs per light, old ones only have 1. We simply got 2 more and spliced them into the harness. Thats about all there is to it.
