My car doesn't have the ***** to adjust the rears. Do you leave them both on the shocks with the seat fully positioned or do only have one that you keep in the glove box until you adjust them?

 

Mine came with one white plastic adjustment **** that I keep in the tool kit.

 

You don't need them. I use a small pair of locking pliers in the interior, going through small slits cut into the carpet for access (not noticeable at all). Actually easier to use than the white piece.

...and yes, you only get one white adjustment ****
