It would be unusual for you to have a wiper arm connected directly to the motor. You probably have one of two mechanisms, most likely hidden under the scuttle. Obviously both types use an electric motor. In one arrangement the motor drives a crank lever that moves a solid bar back and fore, the spindles for the wiper arms each have a solid bar conecting to the one driven by the crank, it's all quite a sight to see in motion, also takes up space under the scuttle because all electrics and anything else needs to be kept clear of all the moving parts. The other sort, is much more refined, the motor also has a crank (small) that drives an Archimedes screw cable (encased in a sheath) back and fore. Anywhere along the length of this cable a spindle drive can by inserted where a small peg inserted in the screw will cause rotation as the screw moves back and fore, two such drives are inserted, one for each wiper. This type is much more compact and does not endanger surrounding fittings. Well done if you have stayed awake long enough to read this far. Most kit builders use this second kind, it is what was originaly used by BMC cars, Austin, Morris etc and most notably on the original Mini. If you currently have this type then the wiper arm is a push fit on to a splined spindle shaft header, you won't have a nut, you just pull them off, they can be hard to remove. So as pintogogo says, if you do have this Mini type of wiper then you should find what you want at the link below.
