1970 Duster 318 with assorted parts, help

Thanks for advice. I have since found a web site and got this bit of information:

"3. Replace Front Spindles with donor set, being careful not to mix up the left and right sides
(calipers to the front, steering arm/balljoint to the rear) "

Now I am more confused. Off to Doge dealer in the morning and see what they have to say.
