Nor am I Skymangs...but this is how I did mine.
S10 conversion mounts bolted to the chassis. The passenger side will bolt on directly. The drivers side chassis will require re-drilling the two lower holes to bolt the mount on. You can use a 1990 S10 2.8L motor mount as a guide, you'll see what I mean when you have the parts in front of you.
1990 S10 2.8L Motor Mounts bolted to the engine, Anchor brand 2436. You can also use a 1990 Corvette Motor Mount, Achor brand 2713
