electronic ignition conversion for 64 361

My 1964 Newport has the 361 BB. Points are no longer available. Trying to find an electronic ignition upgrade. MSD does not make one for this engine.
Any suggestions? Pertronix? Mallory?

I wish there was an MSD rrady to run to fit, but as near as I can tell there is not.

Thanks, hoping someone has been down this road before.
