Does anyone local to Burscough/ormskirk have a tool to remove the studs from the engine?

One snapped but I managed to remove using a tool I had from my NC24 but it doesn't seem to fit the others.

Need to remove them and replace with new as the rear manifold isn't lining up, spent 6 hours trying to persuade it in.

I have loads of M6 studding awaking to go in but at the moment this is holding up the whole rebuild.
