63/66 Valiants

Thanks for the replies, what I am looking for is what fenders, doors, and body panels will interchange with my 66 valiant. I understand that the 66 valiant front fenders are only for the 66 valaints. But what about the other panels? Also what glass is the same with the 66? Steering column (manual). I'm thinking (SSVDP mentioned) other componuts like steering, suspension, rear ends, brakes are all the same. Are the wheel base for the valiants all the same for the 63 to 66 models? Are all A bodies (early or later) rear ends the same length? I'm in the process of fixing up my 66 and need alittle better understanding what I am looking for/at when I go to a swap meet or wreaking yard. Don't want to buy something I can't use on the 66.
Thanks for all the great info
