340 Engine To Transmission Support

I am in the middle of reassembling a 69 340 and 727 Automatic. So far, everything is going together well, except that I can only find 1 support bracket that goes from the block to the bottom of the transmission. It is on the drivers side. Is there supposed to be a bracket on the passenger side as well? The engine was disassembled when I got it, and lots of parts were in boxes.
