Yes, sounds like yours is in range of the wood block technique with no need for advanced surgery. Add in a bit of carpet on the block if car has finished paint.
I once read a description of a trip to the Packard assembly line in about 1948...
The observer described the final operation about so:
The finished car rolled out to a station where there was a very large man with a little pile of wood blocks...he would walk around the latest car critically eyeballing the doors, and if he found anything he did not like he carefully selected the proper chunk of wood from his pile and inserted it in a carefully chosen location between door and frame. Then he would suddenly hurl himself against the door, pick up the fallen chunk of wood, and close the door...which always fit perfectly as he strolled back to his cubby. Hard to say whether the wood or the fear motivated the door to fit...
