1990 toyota hilux, dx, 4x4 single cab

I just finished spending four days installing acura integra seats and herculining the cab where the carpet was. Then as I was showing a friend around midnight on the day of completion drunk skank runs me down leaving me to a ninja move to get out of harms way. Now I have a torn hinge for the door, a totaled door and a janked up fender.
It was a hit and run. Thankfully in the pursuit that followed I was able to flag down a cop and he caught the person trying to get on interstate leaving my neighborhood.

So as soon as I get police report wed. I will find out her name and ins. information. This leaves me in a bind. I hear in Al if the damage equals 75% of value it is a total loss. The book value is 3200 but as we all know a 90 model single cab is usually irreplaceable for under 5k in good condition.

Does anyone have any advice,info? Has anyone welded a door hinge back on? Should it be tig, mig, stick welded, I have access to all types.
