Need Help Bracket Identification

In Pix 1 & 2, I think the brackets with the square hole are PS brackets. The purpose of the square hole was to allow a 3/8" breaker bar to be used to tension the belt while another wrench was used to tighten the pivoting bolt.

The bracket in Pic 3 looks like an early LA timing marker. The black paint obscures where the hashures and numbers for the timing marks are. On the engine, this bolts to the lower side of the water pump. The curved part of the bracket goes around the vibration damper.
