Some info here.

Thank you very much for the info ! It gives me much of what I was needing/ looking for. I really eat this stuff up !!
*** As it turns out, the reman alt I rcv'd was for a Tiptronic... even thogh I clearly asked for a 6spd unit.
After I *****ed a while, they ended up comp'ing me a reman Bosch unit for no extra charge. ( a net loss of +$220 for them)
The runs great. Lets see if she holds...
