Click to expand...

The 73 4 speed will have the close ratio gearset if it has it's original gearset or it was replaced with original ratio gears.

Close ratio gearset

2.47 1st
1.77 2nd
1.34 3rd
1.00 4th

To spot that is actually has those gears in it when you open the side case the gears will have three stripes on them

I'm trying to figure out if this 4 speed came in the car , looks like the tunnel was cut out to make room for the linkage , so I'm thinking it didn't . any help would be GREAT
