Rotor for my SSBC A1531 conversion

I have had the SSBC 153 kit on my 70 Dart since 2005. One of the big reasons that I used it is it is designed to be used with stock 10 inch drum brake spindles so I didn't have to touch the spindles and beyond when I converted the brakes to disc. If that's what you need there are loads on folks on here that have those spindles sitting around from other disc brake conversions that require different spindles. I'd ask SSBC if this is the case for your kit and if it is put out a wanted ad for 10" drum brake spindles.
