I never fitted that lower support as a solid connection would transmit vibration and I judged it inadequate to do the job.
I would have uploaded picture to show my solution but the web site is down and the Laptop with the originals on is not working either at this time!
There is a thread on it if you look back when the site is back up the picture will display.
So a description will have to do, the site should be up tomorrow if you need the visual.
In my case with a VVC engine and a replacement rear ‘brace/frame’, I used the original Rover mounting and bolted it straight back on to the replacement frame. This provided a 10-15 degree tilt on the engine (within design parameters for the engine ) with the Rover original rubber mount to remove the vibration and mounted to the gear box on its original bolt holes, a very secure attachment.
This arrangement gives a little extra straightness to the drive shafts and a very solid rubber mount connection.
You could do the same and reinforce your original rear frame at the same time. There is a school of thought that suggests that the original frame should be welded in place anyway, which is almost how the new chassis are supplied from Marlin..
If you want a straight original threaded bar with mini ball joints on, I have a new one unused…..!
The thread is there and the pictures show...

Should give you the idea of what I did.
