This mount bolts to the back of a Holinger SG3 gearbox and adapts to the BMW factory E46 non-M 6 speed Gearbox Support P/N: 22316760532. This has been NLA from BMW for a bit so we make our own Strom Replacement Upper Mount
You then also can use the factory lower mount 22316760531 which is the part that actually bolts to the chassis and is cheap and easy to get from BMW.
When you purchase this it only comes with the CNC plate that bolts to the back of the trans and the 8 Allen Bolts. IT DOES NOT INCLUDE ANYTHING ELSE SHOWN IN THE PICTURES.
