Welcome to FTE!
In your other post you say it has drivetrain issues. If you have not bought it yet, let's talk about that and what the problems might be.
F76 = Not shown, but we know it's an F750. This infrequently happens where the MPC and Shop Manual do not have a code that appears in the field.
F = 391 4V FT gas V8
V = Kentucky Truck Plant
P10313 = 1972 numerical series, April 1972 production
174 - 174 inch wheelbase
T = Red / Candyapple Red
F766 = Model code not found in the MPC or Shop Manual
E28
E2 = Red and Dark Red Vinyl
8 = Cab and Chassis vehicle. This combination may also indicate Custom Cab
M = Clark model 285V five speed direct transmission
JQM
JQ = Eaton model 17121 single speed rear axle, 7.60 ratio, at least 17,000 lbs capacity.
M = Ford 7,000 lb capacity front axle with power steering.
24000 = 24,000 lbs GVWR
199 3800 = 199 Certified Net HP @ 3800 RPM
459998
45 = Lansing District Sales Office (starting in '72; Davenport '64-'71)
9998 = Special Order Number
Since this was a special order, that may explain the model and series number not being listed in the MPC.

So it's straight driveshaft from transmission to axle--no 2,000 pound fire truck pump in the way?
Some manual transmissions won't take that--the very common NP435 is one, but I'm not aware of any others.
You can probably find another 5 speed that will bolt right in, but it will take a little searching of the salvage outfits.
I did a search and tons come up.
What are the plans for the truck?
That 7.60 axle with a 41 inch tire (if you have 10.00 x 20s) will give you about 60 MPH at the governed engine speed of 3800 RPM.

I have no experience in the heavy duty truck world and I haven’t even seen the truck in person. In my mind I’d assume there’s a pump somewhere in that driveline. For now I plan to just fix it up so it’s drivable. It may be somewhat of a waste but I figured there was a tank on it so I could somehow figure out a way to use it to fill water troughs for livestock. I was offered a good deal and I’d have to ship the truck from Michigan to Southern California.

I’ve got no idea. The whole thing is sight unseen. Going back to the transmission though, is there anyone you recommend for rebuilding the Clark? When looking online it seems like the prices are just around 1500. That’s about as much as I am paying for the entire truck so it’s a hard pill to swallow.

If you could find someone to rebuild the Clark, I'd bet you're in it close to $1500..... If it's locked up you're probably better off with a replacement transmission, but only a a teardown will tell.
How are the tires?
Brakes?

Tires look fine from pictures but those can be deceiving. I was told they’re in decent condition by the owner too. As for the brakes, I have no idea. I’m not even sure what kind of brakes are on there. Hopefully they’re not air brakes.

Hopefully it will have air brakes but probably not
brake drums for juice brakes are unobtainable and brake boosters are getting rare
Military continued to use the early air wedge brakes up through the 80’s on some vehicles so parts for those older systems are still available, the S cam air brake system hasn’t changed much in the past 50 years
Most Of those old fire trucks had 500 gallon water tank, with that ones front pump it could have up to 750 gallons but unlikely with only a 24,000 lb gvw rating
Our 2010 IH conventional cab pumper has a 1000 gallon tank but it has a 32,000 lb gvw rating, with all the equipment and 1500 gpm pump it make be a tad over

Parts other than drums are available through various suppliers, sometimes even NAPA has them. The wheel cylinders have numbers on them and can be researched that way. Bearings and seals also have numbers that can be cross referenced. The brakes may be used by other makers, and the Eaton axles are certainly used by multiple makers, so those parts are available with some looking.
Drums--not so much....

You might take a close look at the carb once you have it running. Check for leaks etc. Check any vacuum hoses for leaks.
You should have a governed Holley 4bbl on that. Rebuild kits are available and may improve fuel economy with a new power valve and fixing any leaks.
See how that pump is driven and check that mechanism as well.
