OK, now a bodywork question. I know the frame is going to come out from under the car, and I see in a couple other threads that it's easier to pull the front end as a clip- sounds good so far! But I need to replace the trunk floor. Should it be after the body is back on the new frame and bolted down, or can I do it while it's up in the air? I don't want to tweak anything, and the only trunk floors I've replaced were on Mopars, not a full frame car. I must say I do prefer GM's in one aspect- it's nice to be able to unbolt the frame instead of going the spot weld cutter/ air chisel route!
