If you have the flywheel neutrally balanced do you still have to use the small shims that go on the flywheel between the flywheel and the discs exactly they way they were on the flywheel? The reason I ask is I had them on the flywheel when I took it to the machine shop for them to balance my rotating assembly. I dont know exactly how many was where so I need to know if it would be a big deal if I use them or not and if I do need to use them is there a way to find out how many go where?

Thanks for any help in advance.
