wiper linkage bushings

[GoMangoBoys]

I am restoring the linkage arms for the wipers and the bushings are bad.  What are the correct replacements for them?  We have the 3 speed wiper motor if that matters.  The bushings are brass it appears.  I see replacements that are white nylon plastic, and that seems fine to me, but they all seem to have a square key on the side.  There does not seem to be provisions for this square key on my linkage arms.
Thanks

These seem to work https://www.ebay.com/itm/71-GTX-CHARGER-1970-74-CUDA-CHALLENGER-AAR-T-A-WIPER-2-3-SPEED-LINKAGE-1-BUSHING/203005565933?hash=item2f44131bed:g:HooAAOSwvD5aDHLp

Had a local machine shop make these for me, not cheap, $180./12.

Those are also available from the same seller in 2, 3 o4 4 piece kits, in case anyone missed that.
If I was so inclined I'd buy 4 and replace all of them.

As good as any place to post this.

@Mr Cuda  I bought the 4 piece set from Sylvain, the measurements are from those.

@Jay Bee
 Thank you.  So the bushing heights track the linkage part.
 So if I'm doing them all, I'd need a 50/50 split.
 Now I've found more linkage,  so I'll need more.
 Out here, we use our wipers,  alot. So I assume they are all worn out. Some are egg shaped.

I have a spare 2822291 and compared it to the bought ones. Both ends of that linkage measured as the taller one. I haven't removed my 2822293 to compare it to the shorter one. Sylvain did tell me to pay close attention to the sizes and the orientation. I guess that's why he puts a mark on one side in his video.

@Jay Bee . Do you happen to know the diameter of these bushings and the hole size for the arm on the wiper motor? Thinking of making some. Thanks

[Jay Bee]

I'll look into that tomorrow. I think Sylvain told name the inner diameter is tapered to accommodate the "hammering" in, but I can't remember. I'll pay extra attention when measuring the inner diameters.

EDIT: The taper is on his punches (they're obvious by just looking), not the brass bushings.
