When we come to the Terraplane engine mounting on the Bentley we find that the increase in engine movement causes the gearbox to hit the floorboards. The only way of getting over this is to use sheet metal floorboards. We should therefore be glad if you could get a few sets put in hand, so that we can equip all our cars in this manner as it becomes convenient.
