A general restoration question

Hey all - I purchased a '66 Dart GT a couple years ago and am getting started on the restoration finally.

My question is this - I purchased this car as an "in progress" restoration, in that somebody had started and didn't finish. For all intents and purposes and to save time, just assume in your mind the interior is gutted, dash wiring is out, and the wiring to the rear panel (tail lights, etc) is out of it. With that being said, does anyone know of a good way to source fasteners for this? I am going to have to put the bucket seats, console, dash, etc back in and am just confused as to how I will source the correct screws, nuts, bolts, etc for all of it. I am wondering if they sell kits or what. I searched but didn't see a lot. Thanks in advance!

try Mr G's. that is where I got a set of screws for the 64 I was building for my buddy. I still had to find the bezel screws but the rest was pretty good .
