engine lift brackets?

[William]

Since Flint and Tonawanda supplied engines for all plants I doubt it varied by final assembly plant. The only factory documentation I know of is the ZL1 engine assembly manual. It calls for a number of small items to be painted with black engine enamel, among them the engine lift hooks. Road test photos of the #3 ZL1 show a black front hook. But the hook in the L88 photo elsewhere on site doesn't look painted at all.
