Fuel tank tray to spare wheel tray hardware

I am looking for the correct size screws/bolts that attach at the rear fuel tank tray to the front of the spare wheel tray. I could not find it in the spare parts manual or xk 120 explored.

In the DHC Supplement.
To be totally correct it would be #2-BA x 1/2" hex heads.

But 5 of mine were missing so I used #10-32 UNF pan heads. I figured it would be easier to slide the spare over them than hex heads.

Thanks Rob,
I knew that the info had to be there somewhere, I didn’t think that it was hidden in the DHC supplement…
