what size socket for pinion nut

all my large sockets are at work and its a hassle to take them home and i need to change a pinion seal in a 71 olds cutlass. anyone know what size socket i will need so i dont have to bring home a bunch of different sockets.

thanks

 

Tape measure will help.

 

the car is still together and i need to know what socket before i take it apart as i will be driving it to where i will be working on it.

 

if you bring a 1"1/16"-1"1/4" you "should" have it covered.

 

My 10 bolt Chevy is 1 1/8. Just changed the seal.
