Lost bolt location

I have just inherited a 2015 Toyota tundra 5.7L in a box that has had the heads removed I have found all of the bolt locations but two. I am sending a photo of the bolts in hope that someone on this forum will recognize them or say if they do not belong to this engine.

 

@reywcms @dirtydeeds any ideas?

 

Hmm @Jowett might have an idea.

 

Those look like brake caliper bolts to me.

 

Google AI was not very helpful, good luck identifying

 

This was my thought

 

Look like rear caliper slider bolts.

 

Yes they do look like caliper bolts but are to small also there is a taper at both ends of the small part of the shaft you can also see the oil residue on the small part of the shaft and some type of sealer on the threads
