You might want to call the Schaeffler (Luk) the flywheel manufacture technical hotline and ask them, as they should be able to tell you if they are different. From their web site (see url below) the number is: 1.800.274.5001
Also, I believe the M37 in the part# you provided is the Pelican only suffix.
