Those pilot jets are considerably shorter, but maybe they're worth a try anyway.
If you have pods with a 4-into-1, 32 would probably be too lean. I usually 34 or 37 pilots with pods, depending on the exhaust.
The air screws will mostly affect idle, and not much above that. But the needle position will make a big difference. I would try that first.

The bike runs great on the highway. Then when I get off the highway and slow down to 30-40 with long slow roads to get home the bike just gets worse and worse. Sometimes just lucky to get home. When I get home I pull the plugs and they are just wet amid black.

If those listed at Jets R Us are wrong, maybe shoot them a email or phone call to see if they can supply what you need.
Turning out the air screws will give some relief, but you could also drop the fuel level 2mm and see what that does.

Lowering the needle will make the most difference. Shimming it is a little more complex. With a shim, the needle will bind. To prevent that, you can put a shim wire in the slide to give clearance so the needle still has some play.

This alters the final height of the slide, so you may have adjust theupper throttle stop screw, and idle knob.

The only place the engine is lacking it at very low throttle, in traffic where you are barely moving. Trying to give it just a very little amount of throttle it kind of bogs down easy. If you just twist the throttle a little more it picks right up and goes. Maybe just mixture screw settings??

If it is bogging as you very gradually open the throttle, or hold the throttle at a fixed, small opening, then it may be lean. So then you'd need a slightly thicker shim. These minute changes in shims are to compensate for not changing the pilots. So a different set of pilots may make it easier to tune.

Heh, yeah, old jets are good for restrictors on carb syncs. You can always use the ones you take out for that.
