My 68 has 2 1/2" drop spindles and -1" springs. Stock KYB monomax front shocks.
Out back it has -4" HD rear springs & 1" blocks, adjustable track bar, trimmed bump stops, cpp shock relocation brackets, stock kyb shocks.
No C notch and it will still haul a full dress Harley.
It actually rides nicer with a bit of a load in the back, that's probably due to the heavy duty rear springs.
