Having never looked that closely at my 1934 A7 steering box, I'm not sure if the Seven worm is attached to the shaft in the same way as those on the Bishop Cam boxes fitted to MG J, K, P, N, TA, TC, Morris 8's and others - new worms are available for MG's in 3 ratios. The second page of this article describes how to remove the worm from the shaft in Bishop Cam boxes, though I've never done it.
