Aluminium induction pipe, induction bend and carburetter. 13. Water heated induction bend in place of exhaust heated. 14. New Autovac tank. 15. Special instrument board. 16. Dipping head lamps. 17. RR. wing irons. 18. Modified brackets for rear springs. These are necessary owing to subframe. The question of steering support and steering gear ratio will depend upon the results of the tests being carried out on EAC. cars. In parallel with the chassis for you own use, we are preparing one fitted with the same pieces which can run a 10,000 miles standardisation test. We should like to know whether you require the 25% stiffer front springs fitting to the chassis. The number of the chassis we are preparing for you is 7-EX. The duplicate car for the 10,000 miles test is 8-EX. Hs.{Lord Ernest Hives - Chair} | ||
