My 59 came to me with a smooth case which I later changed out to a rib. It
had a sound in first (the smooth case) that sounded like the sound you hear
when you are going up the initial incline in a roller coaster . .
consistent heavy click that increased with speed. First gear was missing a
tooth or two. I drove it like this for about a year or so before I got a
rib case to replace it with. But with the smooth case you can drive the
car like a three speed, starting out in second no problem.
