By my calculations

Dash 56 real 43

Going from 35 tooth to 38 brings your speedo down from 56 to 51mph

Going from 35 tooth to 40 brings your speedo down from 56 to 49 mph

You would need to be around 44 to get to 44 mph

And 46 gets it to 42 mph.

BUT PLEASE DO NOT TAKE MY WORD for the gear you need. at 25-50 each it is an expensive shotgunning

If you look in the factory service manual.

There is a tire size (you will have to find a conversion chart from letter / English number size to metric size conversion) rear gear ratio and number of tooth chart.

you should do a better job determining your rear ratio if it comes out to 3 3/4 then it is most likely 3.73. if it is closer to 4 then 3.91

the radar on the side of the road is far from accurate, so use your phone or a Garmin etc.

I don't think there is anything wrong with your speedo now you just did not go far enough.

What is the diameter of your rear tires?
