10 thou press fit is very tight. Something is wrong.
It's not unheard of for bushings to get mixed up in the parts supplier bins.
Since TransStar is near you, take the planet and your calipers and see if you can get a parts guy to help you get the right bushing.
You did chamfer the edge of the bore, for the bushing, right?
Edit; they may also have a rear planet so you can compare with yours.
I have sometimes come across parts with either undersize or oversize bushing bores.
Doesn't happen often.... but it does happen....
The factory has selective bushings so they can still use an "out of spec" part.
Frustrating for anyone rebuilding that unit, since we mere mortals don't have access to those selective bushings.
If that turns out to be your situation, nothing you can do except buy/get another planet.
