What is this?

1969 Camaro 327 with PG.  I know it's off the oil pan rail, but I am drawing a blank.  Thanks, Dave

It appears to be the battery cable bracket... it was bolted on with one of the oil pan bolts... missing most of the time

[McKenzieDave]

No, I have those too.  They are larger loops and coated.  Thanks, Dave

Transmission cooler lines.  You are apparently missing the rubber insulators that secure the lines within the bracket.

That's the clip that goes on both sides (under a pan bolt) on cars with ram's horn exhaust manifolds to retain the front two plug wires on each side and hold them away from the manifold heat.

How'd that get in that pile??  Thanks John, it really had me going.  Dave

Wow, those must be long spark plug wires to go all the way down to the oil pan and then all the way back up to the distributor!

[JohnZ]

Yes, they are - and on a Corvette, the front two wires on each side are covered with a chrome heat shield.
