details are given where differences occur between the HSV models and standard Holden models. A series of

instruction drawings describe the design changes and indicate specific part numbers, fitting instructions and

relevant notes for vehicle servicing.

cap, which must be removed prior to undoing the wheel nuts.

CAUTION:

HSV VU whee ls do not ha ve a s teel i nsert an d ther efore r equire wheel nuts with a f langed seat as per th e VT , VT 2
