You can use 62 rear lower quarters, you will have to make the lower rear corner as the 62 has it moulded in for the bumper. I used a 62 for the passenger side and a 61 for the drivers, they were both 4 door quarters. Had to make a filler piece from the dog leg forward till I got to solid metal. The trunk drop down is different for the 62 but I used a repro set of 63 drop downs. I also used the wheel wells from the 61 and 62. I have a set of 62 front fenders I bought on eBay I am going to use, I'm going to have to fill the 62 trim holes and put in the 61 trim holes.
