If someone could post the full text of the 944 tech bulletin that states you should update to the 968 rear camber mounts, I would be much appreciative. Thanks.

Thanks.

I just got back from the dealership. I should have my parts very soon.

Of note: 951 341 023 00 has been superceded by 951 341 023 01 (951.341.023.01)

Also ignore the 17mm spacer part unless you're using a 65mm offset wheel.
