I need to redo my floors and rockers also. Whoever did it the first time didn't line everything up, so now the door gaps are off. I plan on cutting it all out and holding it together with a ratchet strap or cable/cable binders (would have finer adjustments). Then once I get it where I want, I'll tack on or if possible bolt on some square tubing to hold it where I want and brace from side to side also so when I install the new rockers and floors, nothing moves.
