tranny speed sensor#2

I just had a new tranny put into my 143k '92 SVX after a spree of awd burnouts in mud and ice via neutral drops (my bad). My speedo and odo don't work since I'm getting tranny error code 33 (speed sensor 2). I removed it (it's the one in the front right by the front diff. fluid dipstick) to find that the bearing inside seized and the shaft twisted a few times before shearing itself off. All in all, it's going to cost $230 for the new shaft and the new sensor. What I want to know is:
1. Could damage have been done to the inside of the sensor (and thus the bearing) by overtorqueing it?
2. Could an electrical short on sensor #1 have in any way caused the bearing to fail in sensor #2?
3. Could I be emailed at torg0d@wistful.net by anyone with a used speed sensor #2 who would be willing to send it to me at a reasonable price?

Thanks in advance
