Can 1979 Cordoba/300 spindles be used on older A/B bodies?

Found this older article, seem to back up using them. I will still most likely run what I have and sell these off cheap if I get them to help offset the cost of the other parts. Also, I should have enough parts to make a 10.75 inch set up for someone if they wanted.
