I have a 62 Falcon sedan:
I bought manual disc brakes off front of a wrecked Maverick. I also removed the master cylinder and proportioning valve from the Maverick
New reproduction upper A arms for early Mustang fit the Falcon and had correct upper ball joint.
My lower ball on my Falcon fit the Maverick spindle.
I bought sleeve adapters for my 6 cyl tie rods to fit the Maverick spindles. Bolted parts on, a few new brake lines , rubber hoses, rebuild on calipers.
My Falcon stops well
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
