Yep I have driven the car before, It was rolling perfectly fine before I took transmission, shifter and pedal assembly out. I can spin the differential about half way around before it stops moving?

Are my park shoes by any chance maybe stuck on?

I have now MOVED the car by force because it HAD to be moved un fortunately. Now the Handbrake feels crazily weird to put down. Looks like i'm going to be taking apart the rear brake assembly to assess the problem -_-

PITA
