Mine has a Harken furler and I'm not familiar with the CDI. However, I don't think you have to worry about the narrow anchor loker - I doubt any furler drum will fit in there, if that is your concern. You will likely need stainless tangs that attach to the upper chainplate, the proper length so the lower end of the furler drum is a few inches above the closed locker door. I assume you'll have to shorten the forestay.
