I just spent a bunch of time under the VX looking and trying to figure how to pull the old ones out.
From what I can SEE, the left looks identical to the right side. But I now have the part numbers from Isuzu, and they are different numbers.
But, when I google the numbers, it gives me the mounts for the 95 Rodeo, which are not the same as VX, but are the same as the diagram.
So this tells me the diagram from Isuzu is not correct!
They may not have wanted to change the diagram for a difference in motor mounts between vehicles.

I'm considering trying exploratory surgery to see if the left mount will fit on the right.
