... The OP is a newbie and may be trying to figure out how to post photos.. and it may not be worthless to him (just to us without the photos!)..
But... PLEASE BruceC... post again, tell us more about the car, and if you are having difficulty posting photos, let us know and we can help you. Once we see photos of such a nice car, you'll get lots more help!
notes: The cast date for the aluminum Winters Z28 manifolds are all on the bottom of the manifold and can't be seen once engine is assembled, so I'd suggest paying more attention to 'condition' of the manifold than to the date code. The chrome valve covers for a '68 can be difficult to find, but I'd bet once you post a photo of your engine, someone here will find you a pair..
I've got some extra fans, but not sure about the '68 fans .. what pn you need, etc.
