Try the old grease trick.
Completely fill the void behind the bushing with bearing grease.
Then, find something that will fit inside the bushing pretty snugly ( a piece of roundbar, the large end of a socket extension, etc.).
Place this item into the hole of the bushing, and give it a smack, with a ball peen hammer.
If grease squirts out around your round piece, it's too small (in diameter).
The hydraulic action will usually push the bushing out of the hole. You may have to repeat this a few times.
Is the t-18 a new install for you, or are you re-installing it?
The reason I ask, is because when I swapped a t-18 into my jeep, I had to switch from a tube type pilot bushing, to a disc type pilot bushing.
You may, or may not have to, depending on how long your t-18 input shaft is.

There's a fine line between "hobby" and "mental illness".
