My 2.7 2001 Boxster front struts

[Dave the Marshal]

After its latest mot, the tester mentioned that the front struts were becoming quite rusty and I should think about getting them replaced at some point before the next mot.
I have been browsing the www and there seems to be alot of variations B4, B6, etc. The question is, are the struts the same on the 2.7 and 3.2? They look the same yet when I enter my make, model, year, engine size, it appears that they are all different.
I realise that obviously the brakes are different from the 2.7 and 3.2 but surely suspension is the same?
