Gleaner 7000 rigid to MF Rotary 8780xp

Seems to me by looking at the parts book the basic header frame is the same part number so I assumed the hole was centred in the frame my assumption might be wrong I should have measured with a tape.
There are 2 parts books for a 7000 header one MF and one Gleaner.
But like I said by the serial number this header shows as Gleaner R series .

Seems to me a bit more involved than I want to get.
Noticed comparing the MF 7000 parts book vs the Gleaner 7000 parts book the MF auger has 17 table auger fingers while the gleaner R series has only 14. There was a difference in part numbers of the solid drive shaft between the telescoping shaft and the wobble drive pulley. I'm assuming the length is different.
