What is a factory GM "raised hood" worth for a 69 Z.

It is in great condition (Lemans Blue w/ white stripes)

Any idea?

$300-$400 is my guess. Maybe a little more if there is NO rust, no bondo, etc. They were still available from GM until recently and they sold a ton of them over the last 40 years. Original SS hoods are worth a bit more since they were discontinued way before the cowl hoods.

As long as it's a real GM hood in nice condition it should be close to $500. They have also sold a ton of repo cowl hoods over the years so the buyer needs to know what he is looking at.
