3" ZJ springs- length?

i was wondering if anyone had a measurement of uncompressed ZJ 3" coils? if there is a difference in length between i6 or v8 i'd say v8...but i believe if there is a diff it is in diameter ? the ones i have are about 22" but that seems about 4" longer than my 3" XJ coils...and that closer to 7" than 4.5" :scared:

thanks for any help on this

:tear: maybe someone on the day shift?
