Toyota only seem to list the central cartridge itself, the shaft would be included in that.
The part number for a 1996 EP91 Glanza V shows as 17021 HOUSING SUB-ASSY, BEARING
17021-11030 4EFTE..EP91 1 $1,128.94
For a 1994 EP82 GT it's 17021 HOUSING SUB-ASSY, BEARING
17021-11010 4EFTE..EP82 1 $1,128.94
In this case we know there are differences between the two. We already know the intake impellor is slightly larger and the additional blade on the exhaust impellor on the later, improved Glanza turbo. Can't say I've ever measured the length of the shaft (oo-er!) to compare but it's very possible they changed that too.
I would have thought a secondhand blown ct9 would work out a lot cheaper for parts.
