Imagine have a load of motors on the floor taking up space or a big wad of cash in your hand?
That's not how it works.
Here's a better picture:
1 - Forklift repair shop has a warehouse customer saying their battery doesn't last a full shift anymore.
2 - Forklift repair shop looks around and finds a broken down forklift being sold cheap because they can't get it off the lot (it weighs 5x as much as a car). They buy it and transport it back to the shop.
3 - Forklift repair shop lifts out the battery which is near the end of its life, but still has another year or two on it. They swap it with the warehouse customer's battery.
4 - The dead battery might go in storage for someone even more desperate, or, if completely dead, the battery is still worth $0.30/lb, for 1000 lbs that's worth yanking.
5 - The Anderson connectors and some of the safety gear that's expensive to replace and often smashed gets yanked off. The mast and forks get removed, it can be put onto any other lift no problem.
6 - They dump the carcass in a field until there's a slow enough day to haul 3 or 4 of them to the scrapyard.
...
What they don't do is carefully disassemble every component from every junk forklift and then warehouse it all. It's not worth the labor. It's generally not even worth anyone's time to yank the motor out (poorer areas it will be). It's probably been a decade since anyone even asked for one, and if they do need one, they just wait a few weeks until the next scrap heap comes in.

I sent the emails to 40 places. 6 people have called me all saying the same.
People keep telling you, no one is going to take the time to answer an email to help you out on a project. They deal with people interested in spending $20,000-$80,000 at a time.
Its hard to drive to all these places. They are scattered here there and everywhere.
At the very least, pick up the telephone and call and ask if it's okay if you stop by and can have a look through their junkyard for a motor that you could use for a project.
Then drive out to just the one repair place that seemed friendliest. Literally the first one I called hooked me up, twice.
Again, you're ordering salad and struggling with why it doesn't taste like the steak we're suggesting.
