Floor pans generally go in from the top and overlay the rear frames and rockers. I don't know how you could do it from the bottom without a lot of extra cutting. Cross bracing the door jambs (both directions) is a good start. Are you keeping the trunk pan in, or doing a full floor-trunk pan in one piece? If everything I would think a LOT more bracing would be in store, especially if you plan to rotate. you won't have a flat plane (garage floor) to measure from.
X2. You have a rotisserie you bought not to long ago if I remember right. Nasty things can happen if it is rotated w/ o bracing.
Yes, I intend to brace. Trunk pan looks fine and rockers 96% ok (need some patchiing}. How do you drop from top if you have it braced?
