Post '74 cars with points or electronic distributors use this rotor arm.
If you originally wanted an upgraded version, the Turbos used the blue type cap and points
GDC143 and
GRA2130 respectively to contend with extra heat problems. Rover now only supply riveted type contact plates which fail on performance engines so we introduced a blue moulded and riveted type as
GRA2130 because the the standard parts are now unreliable at high revs. This standard replacemnt part has now been upgraded by Minispares to ensure the contact plate cannot move
and is fine for all normal uses.
