Which radius arm bushings?
Rock Auto shows four different part #s for Moog, for a 2WD. One set looks like it has a plastic ring of some sort. Is there a particular part # that works best?

Well, it does say improved design so that may provide a clue that Moog thought they could do better. Note that the front cupped washer is deleted and instead a flat washer is provided.
Personally, I'd opt for black polyurethane bushings. Rubber deteriorates over time (as you know) and poly is really stable. Therefore, yer alignment stays true.

There are 2 parts to the bushings...one is a C5TZ3B203C & C5TZ3B203B...this is the original p/n for the bushings which Rock Auto should show but I know they have been superceded a few times....but they are the same 65-79 for 1/2 and 3/4 ton 2WD trucks.
There are 2 dished washers which go on both sides of the bushing sandwich...

They are the same 65-75 for F100/250 2WD, 1967/75 F350.

Fixed it for you, "Squire" Don. You cannot rely on this '73/79 light truck CD from hipoparts, as it was scanned from an early '79 edition, has errors and omissions.
You bought this CD on your own, cuz when you borrowed the CD's from me for 1949/79 cars, 1964/72 trucks, I don't have the '73/79 light truck hipoparts CD. As you know, my 1973/79 Light & Heavy truck catalogs are on microfiche.

its one thing to say what the part numbers are, but another to say how they are different.. idk if the rods are different diameters or what. I just replaced mine with black poly, they were reasonably inexpensive and they fit perfectly. Based on poly bushings I've used in other applications, they should last for decades, which is more than I can say for the cracked and split rubber bushings I pulled off.
The stock bushings were a different shape than the poly ones. The rubber ones went around that steel ring welded to the radius arm mounts, whereas the poly ones end short of it and leave it visible. Maybe thats one of the changes on the newer part numbers? Not sure.

Got it. Not sure if I'm going to go for poly; the rubber lasted 36 years 
Thanks for the replies!

I recently had to change the RA bushings on 1 side (actually, just install, as the old was gone). The "cheapo" bushings thru autozone had 2 different styles, the old style where the narrower portion was made on just the one bushing, and a newer design that used 2 bushings with 1/2 of the narrower portion on them. The latter were also red, some I assume they were poly...... (worth checking out)
I went with the old style, simply because I was only doing 1 side. That bushing had gotten soaked with oil from a PS leak, and simply vanished. They had just been changed a couple years earlier, the the other side was still in good condition.
I'll get around to doing both sides with poly, at some point.
