speedometer gear

[Torrance00]

Hello All

well finally put a pair of 235\70R 15 on the back of my 74 Dart
the previous tire was a 205\70r 14.
Now the question is what speedometer gear do I need to re-calibrate the speedometer
These newer tires are 2" - + taller then 205's
Thanks

hello
thanks for you input, I did locate a site that has the gears, just now to determine which
rear axle this car has and gear ratio.
