Both sides are the same. I heard the swap sides when flipping hangers story but it just isn't how it works.
One thing I ran into on our 71; I was installing new leafs with the later, large spring eye and the spring eye just touched the body with the stock hangers flipped over. I could have hammered on it but I went with aftermarket hangers instead and used the center hole. The height is right where I want it.

i got it done a while back but haven't had time to post. i love where it sits and the pinion angle seems to be ok too. i didn't flip the shackles from side to side as they are identical. i just used some uni-bits and made the holes a little bigger. it wasn't all that bad and it was free! can't complain there. thanks for all the help everyone.

here's a pic of how it looks now.

That looks lean and mean, low and not too slow.
