Santa brought a set of stainless under bonnet screws.
All fitted except one. M8 taking a 13mm socket. It was the only one left in the bag from Grove Components. No washer.
Any ideas?

It won’t be for a horn bracket, you’ve spent a long time looking at those recently.

Or the cylinder head....

Not knowing which bolts you have already replaced, it's a bit of a sweepstake but here are my gambits. Could it be the battery clamp bolt or maybe the battery earth strap bolt?

Sweepstake ! Are we opening book, who’s going to calculate the odds & who the handicap?

Bruce, the thing is that all the other bolts in the pack are M6. This is the only M8.
I was in hope of catching someone who had already done this little job.

The battery clamp and earth strap screws are both M6.

I can live with having one screw over - only just.

If they came as a kit, you could try asking the supplier. Presumably, they would know.

My earth strap bolt is M8 with a flanged head not M6 (Mk1 MGF)

Thanks Bryan. I promised to take a closer look at the whole screw arrangement and then take a photo with arrows for the screws. The owner of Grove Components (a classic MG owner himself and a man who really knows about restoration) expressed an interest in having that. If I can make a success of it, I will post the photo on here.
