Pertronix makes pointless conversions for 3-cylinder engines with Denso distributors that have breaker points. There are two models available, the 1631, and 1632. 1631 for distributors which turn counter-clockwise from the top, and 1632 for ones which turn clockwise. Be sure to check with the Pertronix tech support before ordering to be sure it will work for you. Both are available on Amazon, or on the Pertonix website. One advantage is that they will allow you to replace the factory ecm, with the ignitor, and you won’t ever need to screw with the points, and setting the dwell angle ever again.
