All you have to do is divide the ring tooth count by the pinion tooth count... 39/11= 3.545454... Close enough to run with rear 3.55s.
3.63 gears?

Not sure that'll fit into the dana 30 geometry wise, you'd have to find a tooth pitch that results in 11 teeth on the pinion at such a diameter that it'll fit onto a ring gear with 40 teeth at the same pitch. That's the part of gear design that I find to be really mind-melting and wish I understood better.
Far more than "close enough", factory gears are 3.54 front and 3.55 rear quite often. If you calculate it out, with 28 inch tires (about stock size) the difference between 3.55 and 3.54 can be completely erased (or made twice as bad) by the tires being just 0.08" different in radius. At that point it's just not worth worrying about, the weight of your cargo and passengers and checking the tire pressure while cold vs while hot will affect things more than that small a difference in ratio. You can run up to a couple percent difference front to rear without issues.
