Hi....Anyone help please....had problems with my Micra K10 (1991) stopping..after changing carb and leads etc we think it is a faultly distributor...so managed to get a second hand one (less the distrubutor cap and leads) ..fitted onto the engine ok but the old distrubutor cap will not fit...it is not `tall` enough to miss the rotor arm spindle..so now I have the problem of not knowing what dizzy cap fits it...any help please as its driving me mad.
