Injector tube bracket

Should there be a bracket that goes on the side of the injector tubes to the shell. I have seen a few people put them on.

My injector tubes are aluminium and bolted in place to the shell so are pretty sturdy and strong. Is this bracket on the screen used hero packs or just on the stunt packs to help hold the injectors in place.

I don’t want to put this on just for the sake of it if its not on the hero packs.

If it was used does anyone have a drawing indicator the size of the bracket. And was the bracket riveted to the shell and injector tubes or bolted. Also did it fix to both injector tubes or just the one

Two of the hero packs had the bracket:

The bracket appears to be approximately 1" wide and attached with the same large ■■■■■■ rivets used to attach the mounting brackets to the motherboard. IIRC, the GB1 motherboard mounting brackets were 1" wide; it doesn’t seem outside the realm of possibility that the injector L-bracket is, in fact, identical to the mounting brackets, but I’ve seen no conclusive evidence.
