Front axle shaft endplay?

I am somewhat cofused about what I need to do to control the endplay on the outboard half of my front axleshafts.The short shaft (passenger side) is a bendix style with no threaded end. According to Dr. Vern at Vernco.com:

 "Later style Bendix Joints, without the threaded ends,
use a flanged bushing in the spindle to control endplay. With either style, the
inboard half is restrained by a thrust washer in the end of the axle tube."

Yet on the Walcks site under the listing for the bushing it says; "Spindle Bushing that fits all models with the Rzeppa or Spicer front axle shafts. This bushing is bronze and goes in the spindle. These bushings are required if the Bendix style axle shafts are replaced with Spicer axles."

So does my Bendix axle need a flanged bushing or not?  I suspect it does require it because of the tendency for the Bendix axle to lengthen and shorten. 

Next, on the long axle (driver's side), I have a Rzeppa style axle with the threads on the end. There was no nut on the threads when I disassembled the thing. Does that matter? Should I have the flanged bushing on the spindle for this axle?

What I found on disassembly on both sides are bushings in the spindles that do not have flanges. This doesn't really help me because I don't know what was orignal to this jeep and I know that my uncles did many, many Bubba style field repairs to keep the thing moving.
