Help with diff ratio

I have a 1977 F150 Ranger XLT 4x4, with a 400/C6, it runs a Spicer 44 up front and 9" out back, the tags from the diffs are missing, any ideas on what ratio the 9" may be?
I really don't wanna strip it and count 'em!
Also, any one got the clips on the fire wall that holds the wiper tubes to the lip? I need some for mine!!
Any help appreciated.
Thanks,
Shane

In the tips and tricks forum, if you do a search there is a trick about jacking up on side mark the drive shaft and the tire. Turning the tire and counting the revolutions of the d/s to figure you gear ratio.

Something like that, I can't exactly remember??
