Estudio 207 paperfeed clutch part number

[COPYDOCAZ]

I have a machine that is shingle feeding, I ordered a new feed clutch, part # 6LH51224000 When I went to put it in the old clutch is a spring clutch and the new one is a mag clutch. I have searched the parts book bu can only find the nag clutch part #. Can anyone explain this or give me the part # for the clutch spring for this machine.
Thanks
Me
