Origin. To reduce difficulties of obtaining satisfactory jack. Experimental Test Report. At present owing to the difference in height of the front and rear axles there is great difficulty in obtaining a jack which will fulfil all conditions. The 6.75" tyres have made it worse. Road Test Report. Fitted to 12-EX. Apart from reducing the jack difficulty, it is a great advantage to have a definite place to jack up from.
