Sweet ride. I have a 63 falcon futura myself. I read that you wanted to lower the back 3"? I just did that to mine. Here's what I did: Since the falcon has such small axel tubes, you need to get new u bolts bent up. I had a spring shop bend them for me and the cost was cheap @ $35 bux shipped with nuts and washers. Have them bend them out of 1/2" threaded rod with a 2 1/4" inside radius with about a 10 inch length. You'll also have to drill out the spring plates to accomodate for the larger diameter bolts. I wouldn't go 3", I tried it on mine and it was TOO low and rubbed a little over bigger bumps. I also installed new monroe gas matic shocks when I did this. Seems ok. Next step for me is to change the strut rod bushings up front and to whack a coil or so off the front!! good luck.
