Fastrakr - If you are asking me, yes all my mounts are filled with window weld. It was too late though, the extra grip from my tires i think caused my engine to move around too much which is why all my mounts broke in the first place. I had the trans mount fail again and am in the process of making a new bracket to mount the transmission to the stock transmission side mount replacing the two piece bracket. I'll start a new thread when it's done.
As for filling the mounts, don't fill them completely, it makes the car vibrate a little at idle and a little louder as well.
