I have gutted and re-cast three sets of SDL engine shock mounts over the past two years.
When the owner found out the cost of new shock mounts, they elected to (emergency repair) try Polyurethane Construction Adhesive "Liquid Nails" – No. LN-950.
All I can say at this point is if you clean - prep the parts, follow product directions and allow it to cure, Liquid Nails will work.
Of the six, none have failed yet.
I am experimenting with Urethane of a hardness between 60 and 90, as alternative to the high cost or lack of new rubber parts.

b. Shore 40A = Pencil Eraser
c. Shore 60A = Car Tire Tread
d. Shore 70A = Running Shoe Sole
e. Shore 80A = Leather Belt
