Thanks for the reply.
I found this reproduction deep grove alternator pulley is it a good copy or average?

If I can't source an original maybe this is a good back up?
I'm starting from zero as I have no knowledge about these pulleys other than seeing them on cars at the track and shows.
I have come across two factory numbers/codes for this style of pulley W-645 , KW-608 anyone no what the difference is ?
Thanks
Bernhard
