Here's an example of a post from an original owner claiming to have a painted lid. I'll stop posting on the painted lid topic.
http://forums.hemmings.com/viewtopic.php?p=7706&sid=b121a93267c6f2654bce2a460ff473d5I've attached a picture of my engine. I appreciate that the valve covers & air cleaner are not original (in the process of being changed) but someone went to the effort to find a part to cover the upper heat stove opening when the original heat stove pipe was removed. If someone knows where it came from I'd sure like to know because it looks very original/GM like. It's not something a non-OEM supplier would likely even bother with. Is it from one of those dealer dress-up kits some talk about?
