In case you are searching for detail on rubber flex disks: I was checking for my 02/98 E36 M3 with automatic trans the possibility to use a flex disk from the M3 with 5-speed. BMW ETK just showed the bolt hole numbers and diameter which were same 96/6. I found after a long search a site where I got all the details and the difference. In this case

So whenever you are in doubt what fits, search for the correct part number for your car in the ETK and then paste that in the search by OEM part number in the above link and you get the details.

FLEX DISC (Guibo) SERVICE NOTES:
There is a right way to install the flex disc. On the rim of the disc there are alternating triangular arrows that point to each edge of the flex disc. This arrow is where the disc should bolt up to the metal lobe of the driveshaft and the transmission flange. The photo below shows a disc that is NOT installed correctly. This can cause vibration and noise issues. BE SURE YOU CHECK THIS!
