As I recall:
The fronts are a no brainer. They sit in the perch in the LCA (only one way). There are a couple of little holes in the LCA and the pigtail end sits between those holes (the holes are the indexes).
On the rears, the pigtails both point-to the drivers side. This is important.
Others will be able to confirm my less than stellar recollections.
Good luck.

Going to resurrect this old thread for some clarification. Do the pigtails at the TOPS or the BOTTOMS of the rear springs need to point toward the driver's side? More specifically, do you mean that that the very tips of the springs point "left" (like if you were using your index finger to point toward the left of the car from the spring location)? The Bullitt suspension has been on my car for nearly 4 years, and the right rear is sitting 1/4"-1/2" lower than the left. We had re-used the stock isolators, and they seem to still be ok (considering they are nearly 10yrs. old). Thanks!
We're always talkin about the bottom of the coil. The original reason was that you want a meaty part of the coil on the LCA perch. If the coil ended at 12 o'clock (as seen if you sat at the rear bumper, looking towards the front of the car), the end of the spring could be the main contact point in the suspension when it's at droop. So basically, the spring pigtail is placed as far from this position as possible.
I think you got it with the finger analogy. If the bottom of the pigtail was a finger, it would point towards the driver's side. This applies to both sides (driver and passenger) for the reason mentioned above (the contact patch on the LCA).

Thanks, HISSIN50! I'll pull the rear wheels this weekend to check the spring locations. Anything else that you know of that could cause a droop? Maybe the isolators are shot, but is it also possible that the spring could be sagging? They are 250lb. linear rate springs on the rear (600lb. linear in the front).
. I think I'll try to see mine without pulling the wheels.Modern springs really don't sag per se. The isolators being shot is a real likely deal. Or the unibody being slightly tweaked is possible. When I put the Mach 1's on the fox, the original isolators came out. Wow, they looked like baked dung.
You might just need to shim the spring on the low side. You can use a knuckle inside the coils (kinda ghetto) or use a perch spacer (Global West and Steeda sell them IIRC).
One thing to consider: It's been widely accepted that the cars are pitched diagonally. For instance, if your RR is low, is the LF a little higher than the RF? This was NOT the case on my fox, but it seems to be an accepted philosophy on Fox chassis cars (which ours are. Fox IV). On the fox, I was able to raise the LR (my low one) up, and it actually brought the RR down a little, so as to even it out a hair. Not that this applies to you - just my experience tinkering around with this crap. My 94 (Prokit) sits right-on all the way around.
Good luck.

Which got me to think about where one measures from and the assumption being made. If one is measuring from the ground to the bottom of the fender is it reasonable to assume that the measurements should be the same from either side to side of from front to back. I can forsee that these reference points might not be the same due to assembly differences. So where are the correct reference points? Has anyone tried a laser leveler both side to side and front to back to confirm the reference points? Maybe at the end of the day it's just a visual thing. If it looks right that's all that matters.
We think alike. I normally only worry about unevenness because of the aesthetic. So [personally] I measure height from the ground to the top of the fender arch. I do all my tweaking to alter that (and only that really).
The laser level is agood idea - I've just never even really considered it.

Same here...I'm simply concerned about the aesthetics.
HISSIN50, to answer your previous question...the car has exactly the same amount of fenderwell gap (I measured from top of tire to the fenderwell lip in level concrete garage), on 3 of 4 corners.
