cbcb-- this is just my 2cents worth.... There is a formula in the Protein Power book (by Dr.'s Dan and Mary Eades). This tells you your BF% (obviously not as accurate as the dunk method, but a good close estimate). You can also find out your LBMass as well and they take it to the next level of calculating your protein requirements to maintain that LBM. There is also a chart in their book on HEALTHY bodyfat% for all different age groups (men and women). If you don't have the book and would like me to figure it out for you, let me know.
Incidentally, the last time I figured out my own LBM (I am 5'3.5"), it was 109.
