Welcome to the forum,
Looks like you have a great car to start out with. It will be real nice when you get it done.
I also have a 69 Javelin, here is the build thread,

When I started on it, the Alfano and control freak suspension kits were not available, so with the help of Scott Mock, I used one of his C6 front subframes and welded it to the car. Still working out the rest of the details out
