Repair or replace?

[theironman]

I have been wanting to purchase an old chevy to drive and eventually throw money at and found a 70 c10 for cheap that is in decent shape. Biggest problem is that it has been hit in the passenger door, caving it in. Pictures below, I am wondering if the damage could be repaired at all to the point of slapping a new door on the cab or would a cab replacement be the way to go. Don't have much money to put into the truck now. The cab is in good shape and I hate the idea of pulling it off for a crappier great plains rust bucket. It is hard to find a decent part truck or cab near me that is in my pay grade or hasn't went head first in mother nature's rust treatment.

Let me know what you guys think and thanks for any feedback.
