stock corner sprung masses?

I am calculating front and rear ride frequencies for a variety of springs that fit our cars to help me make a future purchasing decision. A key input that I don’t know the value of is the corner sprung mass. Does anyone know what good estimates would be for a 92 LS with manual transmission, front and rear? FWIW, I have been using 770lbs for the front and 490lbs for the rear, but I’m just guessing.

I found corner weights in this thread, but I’m not sure how much unsprung mass to remove, or if these are really stock numbers:

Replying to myself - I worked backwards from DB2-R81’s post in http://forums.g2ic.com/showthread.php?32820-spring-rates, and came up with corner sprung masses of about 740lbs for the front, and 465lbs for the rear.

If anybody can confirm or correct these figures, I’d be much obliged.
