Help with 1970 Dart restoration please.

I need some parts to move on with my current stage of restoration and need to locate:

Vendors for:
1. a correct emergency brake cable setup without an intermediate cable. The one I see at least on Mancini doesn't look the same as in the picture.

2. Fender, front and rear valance bolt & U-nuts. Vendors claim that the The zinc phosphate finish is much more durable, resists corrosion and takes paint better than the OEM black oxide.
Ay opinions on this?

3. A passenger side fiberglass fender extension

Body assembly:
I am trying to bolt the body together and send it to the body shop to complete the panel assembly and at least prime it so it will be sealed for the winter. I was hoping for some input because I don't want to purchase fasteners that aren't going to look right. It's never been assembled since I purchased the car but I believe the panels I need to be able to assemble should include:

Fenders, doors, hood, front valance, hood latch assembly, trunk, fender and quarter extensions and rear valance? Am I missing something? Always been a B-Body man till now...

Thank you in advance for your input.
