The left front cab mount has basically no movement; the other three have enough to adjust the cab somewhat. The core support should have quite a bit of adjustment with the nut plate setup. You may have the core support pulled down tight on the frame horns with the mounting bolts (where it needs to be shimmed) and this is what is making you think you are out of adjustment. Make sure the metal spacer sleeves were in place when you mounted the support.When tightening the core support bolts and you see the core support pulling one way or the other, shim until this doesn't happen. It should just be resting on the frame when everything else is adjusted. Also, as mentioned above, the core support is the last thing to be tightened as you work your way forward. Keep us informed
