Just to update this, fitted the bulkhead yesterday with 16mm tech screws.
Was waiting all week for ford to get back to me with a price for all the bits but had to be fitted yesterday.
One thing to note, without the gasket on the bottom, the bulkhead is 3or4 mm lower than it should be.
Not an issue for me but just putting it out there.
Once again this forum has sorted me out, thanks to all who posted!!
