E-350 engine battery rail nut pack

[phlite]

Odd subject I know! On the e-350, the engine batteries are often mounted on the frame below the passenger side barn door. I need to replace a “nut pack” that the bolts holding the the battery housings to the frame screw into. See pic attached. Anyone know the part number or what the “nut pack” part is called?

I believe it's called a "battery box bracket". Look up PN N808992S301.

I relocated my hood battery next to the frame rail battery. I used ss hardware, just normal bolts and nuts when bolting the battery boxes back up.
