On a 65 Custom Sport what does the heavy suspension include and was this option added when the 409 was ordered?

I don't know if it came with all 409's but it included different springs, different shocks and an additional upper control arm on the differential. (3 arms on the diff vs 4 arms on the diff)

Was wondering if brakes are different also?

No, they all had the same diameter and width of brakes for 65. I think the only option would have been metallic linings.
