2' by 2' by 2" concrete paving slabs (Sheriff Hutton YO60)

I'm re-arranging and extending some paving in my garden. The existing paving is these very large, very heavy 2 foot (610mm) square by 2 inch (50mm) thick concrete slabs - do you have any you don't need? Or there used to be a 2 foot by 1 foot size - those would do. I need four or five of the big ones - or the equivalent in smaller ones, or some combination of the two.

New slabs come in metric sizes which don't fit with these - frustrating! - as to do the job, I'd need to buy a dozen new ones - and then throw away eight perfectly serviceable old ones. (And they're not easy to throw away - council tips don't really like you dumping masonry and rubble - loads of rules and limits).

I'll come and collect whenever you like if you have some. Happy to lift them if need be, and I don't really care if they're old and dirty, as long as they're whole.
