A nut and ferrule won't cure this type of hose fitting configuration.
He needs to remove the old fitting, place on a new 90 degree bead lock FM o-ring style fitting with the R12 schrader valve option on the existing hose, crimp, use a new #8 o-ring at the compressor side, and swap over the pressure switch. The existing flare fitting at the condenser side will re-seal as it is aluminum.
Replace drier.
Add 1-2 ounces of refrigerant oil to system.
Evacuate, charge and test.
