Suspension/Steering component difference, Drum vs. Disc
Did a 65 Barracuda even have 10" drums as an option? OP may need spindles as well if they didn't. That brake kit looks like the one SSBC sells. I had a nice set of those with spindles that I sold a year or so ago. They are nice brakes. The only thing I raised an eyebrow at was the spacer that goes between the seal and the spindle. :realcrazy: Drum brake spindles need the drum brake ball joints because of the smaller bolts, as JYH mentioned above.
