Have some questions about a 5.7 swap into 73 Charger

Not only do I have everything I can get just about anything he could need that's a factory part. Need a air box, want a fuse panel from a Toyota? Need a plug? Axle, or even a trans. I have access to alot for good prices. When it comes to ram stuff the deals I can get are hard to beat. Using tincup's numbers the harness and PCM would run 1700. And I'm selling allthat plus more for 800. I'll Gide the OP first dibs, but eventually it's going to go up for anyone who wants it.

I'll know more about exactly what I need in a few weeks. Is the harness modified or stock? Thanks
