Hey guys- I recently had my transmission rebuilt on my 2001 Nissan Frontier Desert Runner. While the mechanic seemed to do a good job on the transmission, some parts were put back together wrong and there were missing bolts. I took it back and they fixed that but now there are two missing bolts that were holding up a small metal heat shield (I’m guessing) and I can’t for the life of me figure out how it attaches. There is no way I’m letting them touch my truck again.

This is a partial view of the piece.
It is attached to a red cable coming from the drivers side catalytic converter. Any help is appreciated. Thank you.
