I am brand new to this forum so please go easy on me.

I am working on a 65' 4x4 that has a bent frame from a frontal collision. I am not sure if there is any hope for getting it straightened.

So, I would like to know what are my options for getting another frame?

1. Does it have to be a 65' 4x4 frame?
2. What other year frames can I use (64-66) or (60-66) or (60-72)??
3. How hard would it be to convert it to a 2 wheel drive?

I am sure there are thing I am not aware of so that is why I am here, I was told this is the best place to get help.
