Bolts for a Head Unit in 2010 Toyota Tacoma

Does anybody know what type of bolt, that holds in the head units? I was fixing something up and I unscrewed one of the bolts and it fell in one of those crevices so I am missing one bolt. Either size of the bolt and where I can get one, or how I can recover the bolt by taking things apart inside. Any help is appreciated thanks.

 

Undo another...... Head to hardware store with it

 

I tried that but it is difficult because there are two different thread diameters on the bolt itself. So it's almost like a custom bolt.

 

Should jsut be a 10 mm bolt

 

Well that's screwy...... U may wanna call the parts dept. Some are open on Saturdays. Not everything at the dealership is expensive either.

 

You wont find the same bolt as stated above(unless you go to a dealer), but you can use a 10mm bolt and it will work perfectly.

 

Alright great, thank you. I try to avoid the dealership at all cost
