Then in 1951 the new seat tracks with the rod were introduced. The tracks themselves were much improved as they had a better ball bearing system and were designed so spilled drinks did not gum them up. This style continued from 1951 through the 1955 1st Series. https://www.flickr.com/photos/advance-design_parts_co/8251910066/in/album-72157632186114015/ | | |
