Spring cone style suregrip

I get them at the Ford dealer. They come in a package of; chit I forget how many....... maybe 4. Sorry no PN.
I showed up at the counter,with a side gear and the old-timer reached back and when it came back, there was the right part in his palm; That's my kinda parts man.
I set the turning torque to minimum 100 ftlbs with the correct oil pre-installed. Maximum 120 or it will be a spool on the street.
