Well, he's got a point. But I suspect there aren't a huge number of kits available within a particular carburetor "family" is there?
Regardless of the carburetor you're working with, and whomever's carburetor rebuild kit, there will pretty much be always be parts left over, ones included for similar units. The important thing is that a specific or particular kit covers all the bases. Keep in mind carburetor kits don't include floats or jets, and if you happen to live at higher elevations a different # power valve (economiser) would be needed for your application.
The important thing is to get it clean, all the tiny orifices, make sure machined surfaces are true and flat, there are no vacuum leaks, use new gaskets, and set it up on the bench and ready for final calibration on the engine itself once running.

Mike's only has 2 kits for the 4350 (which is what I THINK it is) so I picked the one with the gaskets that look like what're on mine. There're no floats or jets in the kit? Can I reuse mine?

The brass type floats can be inspected for pin holes, give it a shake and listen for fuel sloshing inside. Bring a pot of water on the stove to a boil (when SWMBO is out shopping, perhaps?) and then set off to the side. Submerge float completely and look for a tiny stream of bubbles. Any of these defects would be cause for rejecting the float.
The jet size is calibrated for the carburetor, but after many years there's no telling what might be installed due to previous "Golden Screwdriver" mechanikers. Be sure to check the # on jets and compare with the shop manual specification. Also beware sometimes people have been known to drill jets out to a larger size, so the # on the jet isn't necessarily reliable. A hollow ground blade screwdriver that fits the jet tightly is necessary to prevent damage.

Your carb is a 4350 late model truck application. The bit that is slipping on you is the accelerator pump adjuster. Rebuild kits will not include it. and that bit is no longer available. BUT the choke adjusting nut from a 4100/2100 will work in a pinch (see below link).. The jets are the standard 5/16" thread Autolite/Motorcraft jets. The float should be the nitrophyl float so it should be just fine.
If you rebuild it and it still not running right dump it and replace it. The 4350 was not a very good carb, they several engineering issues right from day one. Ford actually had a program where they were replaced with holley's (and yes that included swapping the intake.) Since yours is still hanging on it likely was one of the better ones.

If it is running good no point tearing in to it. And they all weep a bit as long as you are not getting actual wet gasoline leaking I would just leave it. You could try snugging the screws up a bit.

The are pretty simple to rebuild. If you do rebuild, read the instructions all the way through before starting...when you get to reassembly, it will tell you to reinstall the metering rod hangar with the original clearance...I didn't measure mine during disassembly, and I completely disassembled every part for cleaning...
