K Series Alternator Bracket

[Smitters]

Does anyone know the part number for the alternator bracket - that is the bit that is attached to the engine block and to which I attach my Lucas A127 style alternator to? Refitting the alternator last night and the front mounting bolt, the short one, stripped the bracket thread. And yes, I was using a torque wrench. And yes, it was below the recommended torque. I f'ing hate bolting into aluminium.

Alternately, I may just use a long bolt and put a nut on the back - anyone tried this?

Ta!
