shuffled disks by mistake

Hi,
I have 6 WD800Jb disk drives. I used 4 of them in a RAID5 (using the
whole disk - no partitions) array.
I have mixed them all up, and now want to get some data off the array.
How best to find out which drives were in the array?
Here are the partition tables (obtained using fdisk on OS X):
