The 1969 AIM specifies the spoiler-to-lower valance bolts as #9417075 #10-24 x 3/4" with a captured washer and #10-24 nut with captured washer #3759924. Do these bolts look like originals?

Not too short Eddie? 5/8" vs 3/4" in the AIM?

Have we been giving lengths as overall?
I sold MRO supplies for Bowman fastener company and we always gave measurements from the seat (bottom face) of the bolt.
I would say that is 1/2" long.

Should be shank length, not overall including head.

Yes, of course (momentary lapse) thanks James.  

Anyone with a photo of a set of original spoiler bolts/nuts?

Nope. Those bolts in the photos have integral washers (washer heads), and the originals had "captured" washers, which are free-spinning, to avoid tearing up the plastic spoiler when they torque up.

Do-over...

Do these bolts appear to be original and correct? Does the "E" head marking correspond to a known (mid-1969) Chevrolet fastener supplier?

AMK lists their 'G-4320' kit for the '69 Camaro Z28 front spoiler, and says:  CONI SEMS, HXWA SCREWS, NUTS, WA'S    28 pieces,  $8.00

Has anyone purchased this kit who can tell or show us exactly what was included?

Lloyd, those look like some bolts I've seen on my 68.  I just can't remember where.
