I apologize in advance if this has been covered but I completely suck at searching this site (is it just me? :o )

Can anyone tell me what chemicals/components are interchangeable between c41 and E6?

I would assume the first developers can be used with either process but the color developer would not due to the chemical reversal component in some?

Are the bleaches the same?

Fixer should be the same?

What about final rinse.

Thanks for any insight here.
