Got it, figured out its easier to take the cable off the tranny completely, pull the cluster out, install the speedo cable from inside the car through the firewall and push it onto the back of the cluster, then reinstall the cluster and dash components. Go under the hood and reattach the speedo cable to the tranny! Took about 10mins as where I pulled the factory cable from the tranny and broke it trying to pull it too much from inside the car, I learned how to correctly remove the cable from the tranny in the parts yard and it went really smooth. Hope this helps someone in the future.
