Tires/Gears Locked?

So one day i was driving threw a city racing around

While i was turning into a parking lot the front of my 92' Saab 900 bottomed out on the front cause it was a semi steep entrance :banghead:

After that happened the car started sputtering, as if there was no gas or i was about to stall.. So I just held the clutch and rolled into a parking space

After that, it would run fine if i was going over 10mph, until i got stuck in a neighborhood with speed bumps, when i was slowing down to go over a speed bump my front tires locked up completely and i was stuck on the bump..

I was in the middle of the road and had to get off, so i just floored it until my car started to move, it didnt want to it jumped a few times and then stopped completely wouldnt even attempt to move :banghead:x3

So I had my fiance push my car with her lifted bronco into a parking space and left it there.. That was about a month ago, i check on it occasionally, and today i went and started looking for the problem because I thought it coulda been the brake line being pinched, i highly doubt its that from my looking..:screwy:

I looked under the car and the metal plate on the bottom was dented in looked like it was against the area where the clutch and pressure plate is

Any ideas?

Whats that hafto do with cars?
