alternator help????
 

I installed an after market alternator with higher out as suggested here. It had different connections on the alternator which I modified to work.
My problem is that the nut holding the pulley and fan blade on backed off and trashed the pulley, fan and somehow the shaft threads.
I have multiple problems.
Need a new alternator because the shaft threads are stripped off. The problem is that alternators come without the pulley and blade. Where can I find these items.
The other problem is that I was going to install a stock alternator but it will need the original connector that plugs into the back. I don't have that part. Where can I find the connector?
