I've got new engine mounts ready to go in the car, and they should ideally be joined by a fresh gearbox mount while I'm at it. I have seen this diagramme but it doesn't let me really identify what's replaceable. Is it 578597? Is it available or can I use something in its place?
 
Note that the 578597 I got recently has M8 threads, not 5/16-UNF. Since they come with Nyloc nuts on top, and plain nuts with spring washers on the lower threads, its not really an issue.
Correction - the rubbers have M8 threads, but the top 2 captive bolts are 3/8-UNF!!!
Here is my old mount.

When I got done with this mount replacement , and compared original with new one, it seemed obvious that the new was just the old steel triangle with currently available rubber bobbins fitted. As I had 2 spare bobbins on hand , so ...sliced off the remains of the old bonded rubbers, drilled the centre of each lower face, bolted on the bobbins, and its done. Looks just like a bought one!
