I think the car is still on the lift, to be honest. He's doing this as a hobby-cum-money these days.
The idea is to ship all four mounts to Strongflex and see what they can do. I think refabrication is the most likely route, i.e reusing the metal and substitute the old rubber with polyehturane. He may want to machine a new metal part and then manufacture complete replacements... I don't know
At any rate, this is the only viable way. The subframe assembly (which was the only source of the mounts) is EOL.
