Thanks for all the advice.
I have ordered the diff gears but am going to wait and see how the pinion gears hold out after the dif upgrade as they all look good so far.
Will post some pics when all done..[sm=49_49.gif]

Also I have been told that driving these cars on grass and road will make the gears strip a lot easier and you should only drive then on lose dirt?
Is this true or is that 1 bloke own opion?[&:]

Thanks again
