| Wor{Arthur Wormald - General Works Manager}/SM4/C9713. Re Michelin Jack. X 391. Hy.{Tom Haldenby - Plant Engineer} 9-7-13. Kindly let us know if the Michelin Jack could be used under our Colonial cars if it were made say 2" higher. This would give an extra 4" when fully extended. The point is, would it be short enough to go under the front axle if made longer? Your immediate attention would oblige. p. Wor.{Arthur Wormald - General Works Manager} | ||
