Here are more pictures of the outer sill that needs welding.
Nearside:
Offside:
It looks like a akward weld as it will need a plate under the jacking points. Not sure how to do this. Remove the jacking points?? It also looks like this has been patched before on the Offside

so is this going to be a right can of worms in the winter?
Looks like its been patched on the front nearside at somepoint too:
