I have some 3/4" left over from when I replaced my cabin sole, but it doesn't match the original. The holly stripes are slightly less than 1/4". See picture below. Being under the table and having teak trim around it I doubt if it would be noticable.
Let me know the dimensions you need in an e-mail (no point in telling the whole world how badly you will be hosed).
If you don't have the dimensions handy I may have the old pieces, but it is too late now to look.
