Glass swap question
Any idea if the rear sliding window assembly from a 99 F150 will swap over to a 2003 F250-SD? The one issue I might have (if it fits the cab) is the surrounding trim/seal. It was leaking on the F150 so I used what I had laying around, shoe glue...that will undoubtedly destroy the seal when I pull it so it'll be a mixmaster between 99 glass & 03 seals.
If it is possible, how hard is it to break it down to individual components so I can reassemble it with the good parts between the two? I've seen same year swaps go easily as whole units, it looks like it simply pops out, but never taking the best of two flunkies to make one good unit.
The last owner of the F250 filled the window track with super glue as far as I can tell, but all the rubber is still ok/no leaks.
Not having the extra cabin airflow just grinds my gears.

The short answer to the following set of questions...
... is No.
And no applies to all questions asked.
To unpack that with a little more detail, and identify some reasons for confusion, consider this:
Yes, a 1999 F-150 rear glass window will fit no problem into a 1999 F-250.... an F-250 LD that is. LD is for LIGHT DUTY. The F-250 Light Duty shared the same jelly bean body as the F- 150, and the only way to externally distinguish 1999 F-150 from an F-250 LD with similar cabs and beds at a glance was by the number of lug nuts at the wheels. The F-250LD had seven lug nuts, whereas the F-150 had five during that time period (until 2005, when the updated F-150 was upgraded to six).
The 1999 F-250 SUPER DUTY, on the other hand, has an entirely different body, so different, that it isn't even necessary to note that the F-250 SD aka F-250 HD has 8 lug nuts. It also has an entirely different back window opening than the F-250 LD, even though both trucks use the same CHMSL third brake light / cargo lamp ensemble. And, speaking of what matches in the rear, they use the same tailgates. But not rear window glass.
1999 was the last year of the F-250 LD, and since you are asking about a 2003 F-250 SD, there is no way that the rear windows will interchange between the 1999 F-150 and the 2003 F-250.
As you seek replacement rear window solutions, it gets even more complicated.
The rear gasket should be replaced, period. Otherwise, tiny leaks will dribble down the back of the cab, behind the back wall trim panel, which is behind the seats... in other words... not visible. Water flows down hill, so water wicking in from the damaged rear window gasket will flow down to the left and right rear cab corners... again unseen, as the deepest valley of those corners is behind the plastic rear C pillar trim (if crew cab) or B pillar trim (if regular cab) that covers up the seat belt retracting spools. From there, the water will flow down to beneath the door thresholds, into the wire raceway gulley.
Whenever the brakes are applied after traveling at speed, the water will keep traveling at the same speed as the truck was traveling, since the water isn't fastened to the truck floor, or the gulley beneath the thresholds. So now the water leaking in from the back window has found it's way to the front of the cab, making it appear as if it is a windshield leak, or a heater core leak, when in fact it was the delicately thin membranes inside the rear window gasket that were destroyed from previous owners and glass re-installation cycles where the gasket wasn't changed, because it looked ok, and didn't APPEAR to leak. But appearances can be deceiving. The only way to know the rear window gasket is not leaking is to leave the rear seat and all the rear cab trim panels off, while checking for leaks. Glass installers ain't got time for that.
That's the problem with gasket set rear windows, and is likely one of several reasons why Ford, in 2005, changed to urethane set glued in rear windows. Which presents another problem when looking for donors to exchange rear windows... even though the body style sheet metal is mostly the same between 1999 and 2016 for the steel body Super Duties, the rear glass differs in how it is installed and set, so one must match the glass setting method with the specific part number and genre of the window actually being installed.
It gets even more complicated, because with the earlier 1999-2004 gasket set rear glass windows, there are actually two different gasket types for sliding glass windows. The manual slider uses one type of gasket, but the Power Rear Slider uses an entirely different gasket, which happens to be the same gasket as the Fixed/Solid rear window gasket, and that gasket can't be used with a manual rear slider. It won't seal right.
So... no.

Y2K pretty much covered all the bases. I haven't seen a write-up that detailed in a while, so bravo!
Your best (and probably most legal, as nydiver notes) solution would be to find a reputable glass shop and have them fix everything on the F250. It's likely going to cost you though, since you mention the slider track is full of something.

Just basic, although my record is free of any tickets or infractions & I do under 1k miles a year, the area I live in makes my premium damn near unaffordable. If I move, this sounds like a decent idea after a few months.

I keep finding a plethora of unwanted surprises the further I have to disassemble things. I've been afraid to look (if I take it in small bites the realization of how much matched spray paint & rain hid at sale is slightly less soul crushing) but I think the steel under the windshield might be rotting as I noticed some gray window sealant towards the passenger front of the roof where the krylon has begun its transmogrification into vehicular dander.
On the 99, the rear window leak looks like what caused the front channels to rot then go full Flintstone. When installing a CB back in 2019, thee were solid albeit 40 grit texture floors as I ran the P.A. & antenna...in September when I went to lift the carpet during the removal, the floor came up attached to the carpet in chunks.
As for the lugs, the 150 had five in 99, you are correct though on the 250LD having seven....both struck me as odd having been strictly a gm guy until the past two years, five lugs was only for cars & baby trucks.
Seven came off like fomoco deciding to be difficult instead of streamlining & making interchangeability possible with eight.
