Do you have an FSM, cause it's all in there in the specs section.  Oh 
shhot, I'll just grab mine.  Note, there are lots of subtly different 
springs for SR/GA, Sentra/NX, 5spd/AT, 2/4dr, etc.  For a 1992 5spd SE-R:

		Front			Rear
Wire dia	0.484"			0.457
Coil dia	5.12"			5.12
Height		14.17"			12.54
Spring const.	123			112	(in/lbs)
ID color	"orangex2,light bluex1"		"light bluex2,whitex1"

Sounds like you already have it, but I have a detailed doc on the 
Hypercos I'll send ya separately.
