Please receive herewith the following scheme :- F.CD.912 Lengthened Rear Spring. The above scheme shews the rear shackle with its centres increased from 2.000 to 3.500. This has been found necessary to suit the 7.000 deflection low rating springs. We have combined the Jack lever arm with the shackle, to save weight and cost. Please instruct experimentally.
