That’s an interesting pic Craig. I knew the box sat further back in the Sigma as I don’t think the Sigma has the sloppy extender linkage that the +4 has. But it looks like the bell housing casting has one of the slave cylinder fixing bosses machined off too and a blanking plug. So where is the slave cylinder on a Sigma?
I have no idea Rog i will check tonight. I am sure someone will come along soon though and let us know.
Edit..
Is this it here to the left ?
