Tricky situation, they use 3 stud negative and 3 stud positive diodes. Best bet is to take a good one out and put it on a diode tester, read the characteristics and find a matching number. Or you can buy the complete kit here.

The stud diodes are easy enough to come by.

I don't know what the equivalent of the UK's RS Components is in your neck of the woods. A simple internet search should come up with a cheaper alternative.
