There is mate its normally on a lug that sticks out near the fifth gear plate but it may have been cut off as its the part that comes in contact with the nova/corsa tiebar when converted.

With the F16CR 70 comes up at around 3100rpm. The wide ratio box does it at less than 3k rpm. (taken from my dads Cav SRi 8v with the F16CR fitted)

count the teeth of a pair of gears, divide the output by the input = gear ratio, then compare what you have counted with the lists of gearboxes to see what you have
