Help: FJ front springs swap, sizes?

[tony_4r]

I am in the middle of the FJ spring/Bilstein 5100 swap. I bought my FJ springs from ebay in December, allegedly for 07-12 FJ. I am fully aware that the driver's side is taller and different than passenger's. However, I am noticing that one of them has the same color, number of coils and coil diameter as the one I see in my 4Runner passenger side, which is still installed. The other FJ one, which I think is the driver's is taller and the wire is of larger diameter.
This is what I have allegedly from a FJ 07-12:
Pink(or purple) and gray, 14 1/4" tall, 9 coils, coil diameter: 0.675"
Pink(or purple) and orange, 13 7/8", 8 coils, coil diameter: 0.650"

I wonder if I got screwed and was sold one FJ and one 4Runner spring. I already took down the driver's side, and I was thinking of installing it before starting on the passenger's side. However, I am going to take down the passenger side to have the springs side by side, but from what it looks now, the passenger's side seem the same.

Any thoughts???? I don't want to install these springs to find out later that my 4Runner is tilted. Any one knows if the coil diameter of the FJs should be the same on each side or different? Can somebody please quickly measure these diameters and let me know.

Edit: I took off the passenger's side. There is a slight difference. First, pardon my color blindness, but the "FJ" springs seem pink/gray and pink/orange, or maybe purple instead of pink (see pic below and help me). I originally thought they were blue/gray and blue/orange. My 4runner passenger side spring appears blue/orange, so there is a difference in color. Since it took me so little time to take off the passenger side I will go ahead and install the allegedly FJ springs. However, if someone has the coil diameters please let me know.

Thank you.

Here is a picture of the springs. The one on the left came from the 4-Runner passenger's side and the one one the right is an allegedly FJ cruiser spring. The FJ is taller and has about 1/16 of a turn longer coil. It is also higher, but it could be that the 50k miles of the OEM spring brought it down. I will install the "FJ" ones to see how it looks.

Whoever reads this.... success.... i installed the spring and got an even 2.5" lift.... it may settle more after few miles....

I think it has to do with Toyota's attempt to balance the "driver's lean" that seems to be inherent on all 120 Platforms. 4Runners have specific left/right springs. This might be while aftermarket lifts when made equal on each side (assuming adjustable coilovers here) exagerate the driver's lean effect while its not as noticable with OEM springs. (At least I don't notice it as much on customer's stock 4th gens as I do my own 4Runner... which reminds me I may want to get a spacer for the driver's rear...)
