Yeah 50resto.com is a great place but if you get lost in their pages go to dallasmustang.com great for resto parts very knowledgable and price is good (my exp.) If you need something your best bet like the old man said is ford forum for sale. If its not there just post a thread asking if anyone has what you need, most of us have shit laying around that were never gonna use.
As for Year One get ready to sign over your first born!!!! very expensive, again my exp. with them. But welcome and hope your prepared for a very expensive hobby
