Factory Correct Smog Pump Bracket Bolts/Spacers

[Tommy68]

Hi Camaro folks:

I'm interested in learning the factory correct bolt that was used with the original small block smog pump lower mounting bracket for a 1968 Camaro 327/210 HP. The bolt attached the bracket to the engine block and I believe the head was painted orange. I've attached a photo of the bracket. Specifically, I'd like to know the GM part number for the bolts (I believe three of them were required), any headmarkings, if they were phosphated, and whether if spacers were also required. Finally, if spacers were necessary, I'd be very interested in the GM part number and if they were phosphated as well. Many thanks in advance. Tommy68

PS - the 1968 Camaro FAIM page 81 UPC 6 A6 doesn't have the GM part numbers for the bolts/spacers identified.
