Sounds like a great car. Like the other guys said - don't paint anything, even the outside. They are only original once, and are hard to find in that condition.
Tell us more about the Motion angle.
Also, nice clock - tells me that it's a non-gauge car, but could have a console - which is likely with bucket seats, but not required. So, is it a bucket non-console car? That would be cool, as you don't see that very often. Looks like you'll need some TCS stuff too!
I know what you mean about driving them, I brought my Yenko to work today - perfect weather - what a blast!
PS: forgot to add, you will most likely find a broadcast sheet (not a build sheet) in the bottom cushion of the back seat, passenger side. It is about 5x8 and it will be tucked waaaay up in there, and you will probably need to remove some hog rings to get it out. The '70 sheets don't have as much info on them as the '68-'69's, but since you have an early car there is a chance that you might find the engine code still on there. It's some great info though, so take another look!
