What is the name (or part #) of the fasteners that hold up the transmission coolant lines?

My poor son cannot seem to catch a break. He has a 99' that we are slowly restoring. A garage replaced his transmission coolant lines, but the garage didn't button them up to the engine, they left the lines hanging. A suspension bolt hit a line and cracked it.

 

You'll have to rummage at the hardware store and improvise. I've reshaped these before as replacements.

Also rebent one of these as a hanger and wrapped in rubber tape so it doesn't cut the line.

That makes sense. Thank you!

You might want to check the bump stops in the front springs too, if they are rotted away, they cannot limit compression in the manner intended

 

Looks like it was the bolt at the back/top of the control arm. I'd check the engine and trans mounts too.
