| RR 78B REVISED (10H) (DE 444 6-10-26) BM. ORIGINAL COMPLETED 20.1.27 STANDARDISATION of CHASSIS PARTS. Date 10.1.27 X No. 7425 No. 8435 Drawing No. Part List Description of Parts: ALTERATION TO THE SPRINGS IN CROSS STEERING TUBE. Origin: Found necessary in France to obtain sufficient friction in the steering. Experimental Test Report: This is the minimum amount of friction in the steering to produce stability and to eliminate low speed wobbles. It amounts to 6 lbs. at the wheel rim, front wheels jacked up. Road Test Report: Cross steering tube with these springs in has run 10,000 miles on 12-EX, 7,500 miles of which was in France. Measureable wear on ball .001". Pads in good condition. Weight of Old Part: £ Weight of New Part: £ Difference per Car: £ Negligible. Signature from Cost Dept. that above is correct. My/Rb.{R.
