1959Ambulance.....Thank God for good old G.M. interchangability! There would never be a big enough demand for the reproduction parts manufactures to produce stampings for our cars. The saving grace for us, is that the floor pans for 1959 Chevrolets is exactly the same as Pontiacs. There are 6 pans available. Left and right front, left and right rear footwell, and left and right under rear seat. The fronts go from the rocker pinchweld to about an inch up the transmission tunnel, and from about the front of the seat tracks to about two inches up the dash board. Ames sells them, as does just about all the Chevy repo houses. I recommend that whenever possible, buy from a Pontiac supplier. Without them we would be worse off than we already are for parts......John
