Bill -
It's also interesting to note that the "mini-cooper S" dist. (better?) was
an option on the '67 (only) Sprite. Catalog listings show the same unit,
Type 23D4 No. 40819 for both applications. Later mini-cooper S's use the
23D4 No. 41033 and the Cooper S Competition unit is listed as a 43D4 No. 41843.
