glad you have it all sorted now john
what actually determines the speed is the actual speed sensor fitted into the transferbox. on the bottom of that there are a helical nylon teeth which will be matched to the gear they run off.
now I am assuming the transferbox is the same as the pulsar even though its bolted to an autobox but the gearing for the drive will have been preset from the factory so its irrelevant which mph convertor you fit as it is all determined by the speed sensor gearing.
im not a 100% on that but almost certain
when the box is out on mine il remove the sensor to count the amount of teeth on it but I bet its exactly the same as pulsar
