I thought the coils were the same on the old springs. Any idea on the top and or the bottom? 1971 Nova SS

I am sure that you found out, but the close coils is on the top, and the bottom needs to set in a stop on the bottom. I had one on my 40 on the drivers side, I had to compress with tool and turn the spring 180 degree, I noticed that spring was really bowed. Now it is right and I put my shocks through the springs.
It is a dirty job, I have anger about no instructions to put a mustang II, they only let you get to guess. I am not an expert, but I would like to write a book with military specs, remove and install with illustrations of exploded of all parts in start to end.
I hope you get it without doing it again.

Footstomper told you right, the more closed coil goes to the top, the more open coil to the bottom. Make sure you orient the end of the bottom coil into the spring pocket on the A-arm correctly, there is an indentation for the spring end to fit into.

I finally got the left front a arms, I had to loosen the upper and lower ball joints and compress the spring enough for turn the spring on the stop. While it was compressed I had to release both ball joints, it isn't easy. I had to push the top hat and get a large screw driver to pry and slide the lower a arm and using a jack to keep in place, install the ball joints. Those tools to compress is a fun trying to get the tool parts out of the coil, you have to take at least a bolt from the finger and get it out, then you can get the left part.
Mostly, I have coils of the 375 lbs. Typical coils are less springs and or are easy. Thanks Ericnova72, now I am going back to the garage and finish the brakes, all the lines and routing to proportion valves.
