318 LA rebuild after losing a valve seat

Well, for some reason I'm not able to get the car into neutral to move it out of the garage and into the driveway. I initially thought it might have been a problem with the shifter, but it's disconnected and I'm still having trouble. I can move the selector underneath the car by hand, and the car won't move in any position. The wheels move freely when the rear is in the air, but on the ground, nothing. I had this problem moving it into the garage to drop the motor, but I thought I figured it out.

I'm going to drop the valve body and see if either a) the park pawl is jammed or b) it's disconnected from the rooster comb. Wish I dropped the VB yesterday while I had the pan off changing the gasket and filter! Oh well.
