Thank you very much.
This is important information as one cannot weld or in any way heat these components as it will weaken them. Even heating with a torch or grinding is not allowed as far as I can tell from reading online.
It seems I had my search words wrong. I'm finding some information now.
However I can't find any of the 986. I'm not sure they've used the same steel types even though they mainly used the same moulds. Does anyone have an image of the 986?
And here's one for the 981.
