Sub frame connectors?

Here's a pic of a set of connectors I made myself. The connectors overlapped the rear frames and T'd into the torsion bar frame, I formed the rear portion of the connectors to match the floor so they did not protrude through. I relocated the emergency brake cable to just above the connector as shown in the pic. At the time the pic was taken the connectors were not weleded in, they were just in position. You can also see the nice doner floor I put in the car, I'm an expert at drilling spot welds now!
