1969 z28 oil pan nos
 

HI can any one tell me whats this is worth part 465220

Although not assembly line correct, they seem to bring pretty good money. Have seen them for $600 and up just the bare pan and a lot more when packaged with the studs and corresponding windage tray.

That pan was still available over the counter from GM until almost 2010. Less than $100 bucks at the time.

As for the differences between assembly line and NOS, I wrote this comparison piece 13 years ago: https://www.camaros.net/threads/nos-...l-pans.178450/
