M42 Flex-disk replacement

[royalflush313]

I'm going to be replacing the flex disk soon, and wanted to know which one (smaller or larger) to get for my 318is. (Part #) would be great!

Also, other than the center support bearing, what other parts would you guys recommend me to replace at the same time?

small.
