Rear shock, lower bolt & nut - part numbers &where to buy?

[zefrum]

I need a replacment bolt that secures the rear shock to the bottom plate.

Number 19 and 5 in the chart is what i need: https://www.tonkinonlineparts.com/images/parts/gm/fullsize/050125TN07-104.JPG

Why would I need this bolt?
On my drive from Bronx NY back home to Houston, some where in Alabama, I heard and felt two loud bangs when going over small bumps in the highway. Im pretty sure I know who did this; I've had a door handle and a tie-rod cotter pin disapear along with other crap....

Since the part number doesn't appear to be online, I would just go to the dealer and order it. Yeah, you might spend $10 instead of $5, but it's quick and painless. I know the parts guys are tired of getting requests for part numbers just to have the customer go buy elsewhere with that info.
