Took Interior appart, leftover spacer, help figure out where it belongs. (solved)

Took my new 2020 Taco apart over the weekend to install a stereo system. but, I have a left over part im not sure where came from. go Figure. -- Anyone know where this would go?






List of parts/trim I took off:

Driver Side:
- front and rear kickboards - all trim
- A pillar
- B pillar


Passenger Side:
- front and rear kickboards - all trim
- A pillar
- B pillar


Rear:
- Back Seats
- back cargo panels behind rear seats


I cant for the life of me find where it goes ( not even sure it it came from the truck, had lots of parts in it over the weekend) Any help on identifying where it might be from would be appreciated.

 

Check where the grab bar goes on the passenger side? Looks like a washer of sorts for a larger bolt?

 

Thats for the driver or passenger a pillar covers.. it goes on the bolt under the SRS covers on the trim panels

 

Lmao this looks identical to a post I made a while back, down to the positioning and everything. Did you take apart the driver side A-pillar? if so it's the reinforcement nut on the upper bolt, underneath the trim piece that you pop out to remove it initially.

That's the answer. Shut 'er down, lock it up, we're done here.

 

Thanks everyone, I appreciate it greatly!
