Need help with speedometere

Hi again everyone, Been enjoying my ride but just recently lost my speedometer.
My 62 impala which had a strait 6 235 with a 3 speed manual trans underwent the transformation to a SB350 with a TH350 tranny. Initially
the speedometer worked at first but was short lived. I did replace the cable but can only get the speedo to work with a drill. Therefore it leads me to believe that the drive gear in the trans is gone bad. The driven gear looks okay but until I remove the tail of the trans I don't know what I need for the drive gear. I would like to have a new one in hand before I open this up.
My dilemma is I don't know what I have for a gear ratio in th meatball.
Anyone know what it may be given the original power train I mentioned above? Or is there an easy solution into figuring this out.
I'm not looking for dead accurate, I'm mostly concerned with the odometer reading so I can keep track for maintenance.
From what I've found out so far there are about 5 different drive gears for this transmission from 7 teeth to like 12 teeth. The driven gear is gray in color which I think is 22 teeth. I didn't know to count them when I had it out.
So anyway with all that said, is there a simple easy solution?
