Need a New tranny

So i switched out my clutch a few months ago. it was whining everytime i pushed in the clutch. My brother and my dad said it was because my brother didnt put enough grease onto the throwout bearing. two weeks ago the whine turned into a screetching noise. i pulled the trans pulled the throwout bearing and it was locked up with the top(mushroom-looking half) of it at an angle . the spindles on the pressure plate were grounded down and bent. now the transmission is jacked.

my questions are:

Should i go to a junkyard and buy a junk trans?

Should have this one rebuilt?

Thanks
 
As long as the case is solid (ie. no cracks, chunks missing, etc.), a rebuild would be your best bet.

Get a kit - possibly look into upgrading it to a World Class or something a bit stouter than the stock T-5.
