If you’re committed to ditching the points, Jon G’s suggestion of the GM HEI might be simplest path forward. Many vendors sell a version that is already good to go for the 235.
Just an example:

You’d probably need a clamp they sell as well.
I don’t love the look of the large cap HEI, but I do understand the practicality.
