New commercial mount for 2004R transmission

So that everyone understands what I did to my car.....The upper A body cross member is basically a formed piece of channel (U-shaped piece of metal). I removed a small section of the channel BUT,... I enclosed the open side of the channel (between the body and the cross member). The pics I posted show this very clearly. So even if I weakened the cross member channel by removing a small section of the channel I restrengthened it by boxing in the open side of the channel. So in essence, it's still a piece of channel but the open side is on the bottom side instead of the top side. Since I "put back" more metal (and heavier metal) than I removed it should at least as strong as it was before the transmission swap.
