If you look on the end it will have numbers stamped in it. For example: 1.08, that means the speedo cable is 8% Overdriven
Another example, .998 that means the speedo cable is under driven Compared to the output shaft of the trans.
I found it...right where I put it!! Well was in a pan in the top of my box.
These are the only numbers I saw on mine so it it 30% over driven? That sounds right, remember I said it was reading 45 mph when I was really going about 60mph. Well the math on 30% over at 45 mph works out to 58.5mph so pretty darn close for GPS speed and a 40 year old speedometer.
Also I remembered what was wrong with mine. The shaft was rung off of it...see the pic.
Oh and if you have any of these laying around I would be interested in them, Matt!! Thanks.
