Pro 950 with LU-407 part number question

[oldtech]

I need a paper feed drive plate for the LU-407 the number listed is 15SS-1660. It comes back invalid. I have tried calling KM but the parts inquiry line just rings and then disconnects. I have checked the TB's etc and found nothing on a number change. I was hoping someone here has run into this before and found a good number. My manager is checking into the parts help line problem now but my customer is pushing.
Thanks for any help.

Finally got hold of KM parts they say the spaces in the number are wrong as published. Now the thing is on B/O:(
