Cadillac suspension on a square?

[rs74]

I was just sitting here going through the ol memory file and I remembered this. A guy I know built a coulpe stepside shortys about 20 years ago. I remember him saying that he put in a cadillac front suspension to make it ride better. Now I don't know if he replaced the whole cradle or just the spindles, a-arms, etc.
Anyone else heard of this? I will have to ask him about it the next time I see which may be a while.
