Alternator bracket part

[........]

Hi I'm new as of today I just installed a new alternator in my 2002 leg wagon
The bracket that holds the alternator on the right side has a long rod that supports the alternator, ok when I un bolted the rod ,a nut bracket came off
And of course it's nowhere to be found
Does anyone have a spare I'll pay you for it or can you recommend a pick and pull in the seatac area...thanks
Sparky in seatac
