So I noticed that my rear end was sagging on my 300TD. It appears the bolt that connects the SLS valve lever arm to the height adjusting rod is missing as when I checked the lever arm was hanging downward freely and there was just the rod on the other side.

Is there anything special about this bolt? Or can I just run to the hardware store to replace it?

Of course the valve is leaking, but I have an oring kit on the way from Andrew.
