isn't that Sprague a stock Ford?
I seem to recall that being stated on here years ago: work: Sorry for not remembering the exact application, C6,C4 or ???"



Cab, i remember reading in a magazine long ago about using a C6 sprag. i can't remember what magazine it was, but i'm sure it mentioned a C6, and it was used because it had more springs and rollers in it.
i wished that could be confirmed, or discovered i am full of bullpucky.
