Auto Tunnel Std Mounts

Half way thru installing my auto tunnel into the Mk1 scort. I have just noticed that one side of the auto tunnel mounts has 2 captured nuts for the cross member but the other side only has 1.
Is this normal? I assume not.
I think I have to remove the mounts anyway as the tunnel is rusted out behind them so to do the repair job properly I will remove them, let in fresh metal then remount...... May as well weld on a new nut if its supposed to be there.
