G'day Andrew
I have posted two photos of the right and left engine mounts from an original ex NZ LRDG Chev. This Chev is in an unmolested state and I believe the engine mounts are the originals. Although the mounts are covered in grease and oil, you should get an idea of the set-up.
This is the vehicle the photos come from.
Engine mounts.
I hope this helps.
