I have a 2.5" gap under on small area of my double garage door. I
can't seem to find a bottom door sealer over 1.5" thick. Where can I
find a garage door "foam material" that will be 2.5" thick and will
compress completely in the areas of the door where there is no gap?
Thanks for any help!

Upholstery foam. + duct tape, proly.
They can cut upholstery foam (white, yellow-ish) pretty accurately.

However, I sort of agree with mkirsch -- 2.5" is pushing the definition of a
gap.
But, if you really can't fix the floor/foundation, foam will at least fix
the air/humidity/infiltration problem, for a while.
If this is going to be a longterm solution, think of ways to weather proof
the foam, by wrapping it in 3 mil plastic or some such.

They make a sealing rubber strip (not foam) that you might want to put on
the bottom of the foam, as well. Almost looks like "channel".

You might even be able to scavenge this foam from cheapie mattresses, or old
couches, etc.

You'll want to counterbore this material for a screw and 1/2"-1" washer, and
screw from the bottom. As you do this, you proly won't get a perfect "mate"
between the foam and the door, but no matter, when the door closes all will
be fine.

Another long-shot material possibility is rubber tubing, such as used on
industrial rollers etc, which is a long shot bec this is very expensive
material, but you might find some in a dump, or factory, etc.

I happen to have a bunch from an old machining job, and it's great stuff.
Just loosely stuff it with cloth or old foam scraps, etc, just to give it
some body. You wouldn't be able to counterbore this stuff, but a flat head
screw and washer from the bottom would still be the way to install it.
