Respectfully,, the Falcon car and the Econoline suspension are completely different and an IFS most common on any car. No cars that I know of that would have a straight front axle unless built that way as a drag car,,,? and so my point is that it sounds like you will be both asking a lot of questions about the suspension systems as well as many others....LOL
HIGHLY RECOMMENDED for you to purchase and read this book,,, HE IS VERY DETAILED in regards to many things that you will be asking about,,, I have been recommending this book for many years and an EXCELLENT source.
I expect when you get into the suspension you will need to know and understand things like "BUMP STEER",,, brakes, lowering methods and what you will need to do to accomplish it correctly..
HOW TO MAKE YOUR CAR HANDLE BY Fred Puhn HPBOOKS-46 I can vouch for Tim's reversing kit,, LOL,,, (inside joke there),,, but every vehicle will act differently and you will need to understand what you are creating and how to solve the issues. More than likely your 1st will be the king pins, how to do them, why the OEM pins are not correct, the steering box will be the next if not the 1st one also,, is it gone, does it need rebuilding, how to adjust it for play, etc,,,, How are the ball joints, alignment and very importantly things like caster and camber (again ALL well explained in the book).......
For every action there is another reaction,, and perhaps one of the worst issues with a straight front axle can be bump steer,,,, but none of it good unless you fix the other issues worn out firstly !!!
