Dang.... you ain't wasting any time. Once you get it fitting like you want, you can tack a few places on your filler metal to the inner tub you're moving over, then pull it back out to where you can zip that entire seam together without being turned upside down and sideways...lol. My buddy always puts the decklid back on before welding the hinge supports back together, so he can move them and clamp them in the right place to get the trunk gaps right. He said he learned that the hard way!
