I am replacing my travellers rear compartment set and had to remove the wooden boards in the rear. This proved problematic as the bolts were mainly rusted away. I got them all out with some violence and WD40 and molegrips eventually.

My question is :- does anyone know the size/thread of the bolts so that I can replace with new as the captured nuts are still in place.
I was just going to call up my local Morris supplier but wondered if I could just get them at B&Q instead.
Many thanks for any responses.
Cheers,
Scott
