55 f100 rear suspension front shackle

Doe anyone have or know where I can get a rear suspension front shackle for my 55 F100, I have checked several shops and no one has any and does not know if or when they will.:(

Tons of places to find what you need for your "Iffy" a couple that never failed me.
