Stihl 041AV sprocket part number needed

[AVB]

I have an older 041AV that has 3/8 7 tooth spur drive drum. According to Oregon their 32060X will not fit since mine is on SN 4148930.and image I pul up for the 32060X definitely don't have the hole. I needing the one with the hole in one tooth to drive the oil pump.

Is the 1113 640 2000 the correct part number even I getting references on most sites that is for after SN 5664891?

That seems to be the right number for the star sprocket one.
The one with the rim sprocket is:
0000 642 1220 That's 3/8th 7t
