Can anyone please confirm this flywheel part number
 

Hey guys, before I go ordering a non returnable $500ish dollar part, I was wondering if someone can confirm I have the correct number for my application

I’m doing a 5 speed swap in my 89 260e
I have a transmission that runs a single mass flywheel
I found this part number
103 030 14 05
Looks like it is correct when it comes to have the timing windows on the back for a 6 cylinder
I just want to make sure it’s a single mass

Thanks
