97 AOS Parts Verification

[runjmc2]

I have 105K miles on the original AOS and figured it would be a good idea to change it. For instructions, I found Brad Roberts tutorial with pictures. Since I have a '97 my understanding is using the new AOS requires additional parts and I would like to verify what I am ordering from Pelican.

Based on Pelican for the '97 I need:
1. The AOS: 996-107-023-04-M100
2. Vent Line for Oil Separator, Boxster (1997-99):996-107-145-06-M100
3. O-ring for Vent Line, Boxster/Boxster S (1997-04)999-707-446-40-M127
4. Oil Separator Hose Clamp, Lower (35 X 12), Boxster/Boxster S (1997-02)999-512-630-00-M100

I have seen where Pelican has listed parts that were already included with other parts and wanted to double check that all of the above are needed.

Finally, with the '97 if I need to also change the vent line (#2 above) does that significantly impact the complexity of the job, I don't believe that was factored into the instruction that Brad provided.

Thanks!
