1972 alternator bracket finish

Just thinking out loud....

And this assumed SB Mopar engine

The triangle bracket probably was on the engine before engine paint as water pump bolts go through it. That would suggest it would be engine colored.

If it was added after engine paint the head of the bolt would be engine colored.

Unless they left those bolts out then they would not be engine colored.

I don't know if all engines were ever test fired or if they were put into the car then first fired when it rolled off the assembly line?

Again just thinking out loud.
