Seat mounting bolts

I have a habit of consistently buying the wrong nuts and bolts so in an attempt to prevent this happening yet again can someone confirm that the bolts for the front seats on a late car are 5/16 BSF?

That's what they are on my '71 traveller and a quick search on other threads confirms it.
There's a great thread in the mechanical section called 'Thread Sizes' and details most of the tread sizes on the Minor, no mention of seat bracket bolts though.

On the ESM website they are PAN801 with a 5/16" spring washer. They are pointed.

Forgot to add that I will find some longer bolts so that I can put in a packing piece in order to tilt the seats (original) back a wee it.
I plan to make the packing pieces out of hardwood or Tufnol if I have enough left over from my boat restoration days.
