Ultrium 920 - snapped inner spool

[DavidWatt]

The clear run of "tape" from the white spool inside my Ultrium 920 has been snagged out of it's clamp. It's out of warranty, so I've opened it up and had a look around, but have been unable to find exactly where it fixes to. It has 2 little half holes on the end of the tape that look like they are clamped with 2 screws.

Does anyone know the location of it's mounting point inside the drive? I have a rough idea of the area it goes, but can't see where exactly, without removing the whole mechanism.

Thanks

It seems the part I'm describing is known as the "take up reel".
