Drum to disc swap

If your car has 10" drums then the spindles have to be correct for the 10" drum kit. I have seen both the 9" and 10" and they are not even close to each other. There is a significant difference in the bolt hole locations between the two holes at the top that hold the drum assembly to the spindle. Having seen the SSBC kit and the article on the Wildwood kit, I would go with the Wildwood kit.
