FORD ROCK CRUSHER TRANSMISSION???

[KORNBREAD]

Ive heard of the m-22 or muncie four speed's chevy used but never have i heard of ford having or using a rock crusher trans. Theres 2 posts of craigslists both with 78-79 broncos (which i thought those only came with the c-6) saying they have a trans called a 351 Rock Crusher??
