65 cutlass front a arms anyone know if a 71 skylark a arms will fit or any other a body's and year's for a 65 cutlass

 

Suspension parts from 64-72 should be compatible, as far as I know. There might be a 64-67 & 68-72 split on some parts

 

The arms will interchange. Some of the later LCAs used oval bushings instead of round ones for rear bushing, but the arms still bolt up. Early 64s used metal bushings on the cross shaft, but again they will swap as an assembly with the shafts.
