Its hard to tell in your picture, But are you missing a plate that goes between the trans extension and the cross member? It seems to me that the trans is bolted direct to a plate and the plate has the rubber mounts with the bolts going into the cross member. Does that make sense?? Your picture looks as if the bolt is going through the extension, a rubber biscuit, then the cross member... Is that correct? Maybe I can find a picture of what I'm trying to say.....
