316 throttle cable came loose from the throttle lever

when I went to move my 316 to its "summer quarters" yesterday I noticed that the throttle cable was no longer attached to the lever in the dashboard. I 'm stumped as to how to remove the dashboard in order to reattach the cable to the lever.

at some point in its life it appears there was a bolt on each side of the dashboard at the front/bottom. but with these bolts missing there is still something holding the dashboard in place.

thanks in advance for any advice.
