Well i'm going to swap out the clutch in my Civic, now i have an extra flywheel in my garage but i don't know if it's a B or D series. I want to get it resurfaced if it's a D so i can do the job non-stop. The flywheel I have is 11 1/4 inches from end to end. Can someone measure a D series flywheel and/or a B series to let me know if this is a D or B.

 

I think that i may have found the answer, I've been told that B series have 8 flywheel bolts and that D series have 6, anyone verify ?

 

word thats true
