That car is nowhere near totalled. Tim's car is at the frame shop right now. Talk to Tim and see about getting your car over there. Or call me tomorrow and I will get that guy Mark's number who I told you about. I don't know him very well though, so probably no hookup deals.
Measure from the rear cage bar (one that goes between the struts) to the trunk floor and see if there is any difference left vs. right. Cut a quarter panel off a junkyard car and redo the rear panel. It's really not worth trying to transfer the cage into another car unless it's a 'vert, cause you will end up cutting most of the cage apart anyway, or cutting the entire roof off the new car.
