Looks like 1 of 4 transmission crossmember bolts. it's gotta be 4" long based on the pic. I don't think the idler bolt is that large?

Too big in diameter. I am sure it is the old idler arm bolt, they are very long, large diameter and fine thread. I have a new idler arm and bolt so it goes in the extra bolt box.
