11 blade fan parts

[Martice]

Yeah...I would like if anyone could tell us a complete list of parts needed to install a Porsche fan on a flat4.

1. the Porsche fan/alt
2. the ring machined(this is a task)
3. the shroud
4. the band (strap) that fixes the shroud to the case(stand)
5. the pulley(s)

??6.?? is there a must for a stand or you can bolt it to the machined case? what about the breather box in this case?

We are talking about type 4 in my case.
