Had to build a new gravel pan for the Opel, as solid as the floor was, there was just nothing left of this piece.
The Propane was a success. The Opel GT runs as strong as ever on Propane. But being an old car that sat in a field, there were many other problems, like replacing or rebuilding the entire braking system, windshield wipers etc. But she is now a nice little car to visit family and friends when I'm in their neck of the woods.
