Are you sure you want to connect the rear disc bracket to the engine bolt?

Unless you have some sort of “give” in the disc arm, then you will put the arm under a lot of strain when the suspension compresses.

It would be better to fit the disc support arm to the outside of the engine mount, as this rotates around the engine bolt. A exhaust clamp makes a good fixing to the outside of the engine mount.

I suspect the extra long engine bolt is used on the type of radius arms which have a bearing around the engine bolt fulcrum. This type is supposed to resist the rear wheel torque twist on the engine mounts which you don't get with the outer engine mount types.
