Ebay throttle body breaking throttle position sensors

[Toetag75]

Hey folks, I'm kinda new to the LS world.
I purchased an ebay "G plus" throttle body. I installed the throttle position sensor last night, and this morning i noticed it was cracked. I went to a local junkyard to pickup a new TPS. I went to install it and this one cracked before it was fully tightened and sealed. Its seems the throttle plate shaft seems to be too long and is breaking the cases before its fully seated. Has anyone dealt with this before?
Thanks in advance.

Might not be made correctly. Can you return it?

I stick with Nick Williams Throttle Bodies.

I do not believe i can return the throttle body, its been awhile since i bought it. I may have to get a nice throttle body. I just didnt want to spend a lot on one.
