Consensus on driveshaft with longer splines?

[kwalk]

After heavy research on this forum and other sources I know what my problem is and after letting it (the car) sit quietly for some months now I'm finally in the mood to get this thing done. I think I'd gotten a little desponded about it. My issue is the transfer case. I want to replace parts chain, output shaft and drive shaft. I found good pricing for both parts, but after researching here there seems to be some back and forth about using a longer drive shaft. Some say using the longer shaft still goes out after some time, some say it's all good. I realize that some that still had the problem may or may not have changed the female part, but what is the final consensus? Can you guys give me some advice? What should I do? To get a longer shaft or to not get a longer shaft? That is the question. Btw, my ride has 73k miles.

Also while I found the parts on the net, does anyone know where I can get them locally here in Houston? Thank you in advance.
