I've a feeling you may be based in Australia ? Here's a link to the Accuspark site in the UK and a link to Vince Leek's excellent fitting instructions. The Dynamators are a direct replacement for the Lucas C35A and the C35M (and the earlier DEL) so will definitely fit your 1938 Seven. Yours shown above could be either a C35A or C35M, the model number will be stamped into the steel casing under the silver paint - my 1935 C35A is identical to yours. Note the Dynamators are available in 6v or 12v - negative or positive earth.
