yes and yes and yes ;D................. Top hat, stepped, bolt up.
One caveat - I always like to ensure that the mounts can pivot freely [ cars or bikes ]. The mounting bolts [ which should NOT have thread on the bearing surface ] are there not only to hold the shock in place but ideally should ensure there is no "stiction" at the mount point.
In this application it is a moot point due to the angle of attachment, but stiction does effect the characteristics of the unit. In your example, this is being pedantic.
In a race or competition application these metalasic bushes are always replaced with poly or heim ball type mounts.
Metalsitic joints are in fact meant to operate in that fashion - ie to rotate the bush and the rubber as Crazy states - however take a look at replacement poly bushes which are designed to simply be a bearing, and thus removing any possibility of stiction. Your choice entirely, both methods are acceptable. That is why [ rotation of rubber within bush ] Metalastic bushes will wear out eventually - take a look at a real old shock bush where the rubber has torn or the bush become detached.
On the TR1 units pictured, the spacers are just that - spacers - they don't [ and don't need to ] perform any other purpose than that.
