Diodes appear to be ZR1480. There's only a few that Bosch make, and by process of elimination:
Page 32, part number ZR1480

Given the alternator is 150A, the diodes need to be rated >50A each. All the ones >50A have the same ED-10 package, so the 80A one will work even if the 65A ones are the right ones.

These guys sell em
You need 3 each of the positive and the negative:
