do caymens have ims issue?

[runjmc2]

I expect to looking at a 2005-2006 997 in the next few years and want to be sure I get the updated IMSB design. For the 2005 mid-year design upgrade, is that a M96 or M97? Asked another way, was the IMSB design upgrade only applied to the M97, or first in the M96 for a short period of time in 2005?

If the upgrade was in the M96 in 2005, that would obviously make it more difficult to determine which 2005's had the upgrade. In that case, can the VINs in the class action suit be trusted in this regard (e.g. if the VIN is not on the list, it is the upgraded IMSB design)

Thanks and sorry for taking a bit off topic
