I search for "levers series IIa" and it comes up with some fooker who has "steering brakes" "help stuck in 4x4" and "how to id v8 engine and gearbox help"
Well I went and bought a disco, put it on the drive sawed it up to likkle bits and put the engine in the series, the rear axle is to follow soon, as soon as I can work out the ratio.
Cheers dave, need to get under the car and turn the shaft enough times to count it, I was thinking turn the shaft 20 times (te reduce the error) and working it out.
