Very helpful post -thank you Mr. Roberts.
Here is a thread that has a detailed diy install:
987 MOTORSPORT AOS INSTALLATION - Articles
The price of the part is horrid ! It is a pity that whatever internals make this 98710792600 part so much better can't be found as an upgrade to fit all Boxsters/Caymans.
The problem of using the 996 part and it conflicting with the AIS pump bracket - is this another incentive to remove the AIS and do the ROW reflash ? Thereby eliminating two sources of problems?
I have seen a photo sectioned ,failed AOS .The diaphragm splits apart. replace with a small circle of Teflon/Kevlar/Viton ?

Surely there is a better alternative to a $1500 part or repeated(even more expensive) failures ?
Apparently the much cheaper (but uograded) 996 unit can be modified to fit:
