[TR] TR3 Transmission Tunnel

[terryrs at comcast.net]

To replace the grease fittings to elbow type on my clutch arm, I removed the transmission tunnel.  I did not replace the capture nuts when I rebuilt the car and they've continued to deteriorate to the point where I barely have enough to keep the shape right.  

Is there a workaround for bad capture nuts without having to resort to welding, which would be a tight PIA with the engine in the car?
