| -2- It may be that the Company already supplying us with steel castings for suspension parts, have something to offer on the above subject. Certainly the parts already supplied seem to effect marked economies. As a matter of interest, the Ford crank weighs only 65 lbs. before machining and 56 lbs after i.e. only 9 lbs. removed where previously 24 lbs were removed. when it was a forging.
