I have an assortment of front springs and decided to take a picture to show how they compare.
This may be useful to those wanting to swap stock springs around.
The 11-3/4" long (1 coil cut off) FJD coils were on my GT before I installed lowering spindles.
I needed to return to using longer springs after that.
84 springs are their own group, as 85-87 got new ones with the redesign of the lower control arm.
They are interchangeable however, as I installed my cut GT springs (11-3/4" long) in my Indy to lower it.
See here:

Wire diameter appears to be about the same 12mm (1/2") on all.

1984 DMF 13-1/4" long 12mm wire
