Marty....AIM, UPC 6, Sheet B9, View C (Left side is screwed together), View D (Right side is spot welded together).
That indicates that both are correct depending on what side they are used on.
Also according to most accounts, the left side bracket that bolts to the block was attached to the block at paint time....thus the bracket was painted chevy orange as well as the bolt that bolted it to the block....the rest of the bracket was added at the engine dress process.....actually if you look closely at the View C it even states that the bracket and the bolt was part of the engine assembly. The right side was added later at the engine dress process and none of them were painted as well as the bolt that bolted it to the block.
Now this is the 1968 engine I am talking about....I am not 100% sure that this carried over into the 1969 engine line though. Maybe some of the 1969 people will know more about this.
This make sense.....?
