No reason to be sorry that you're getting after it
Look around the resto forum, lots of good info on building a cradle. Several great examples. WOG did a really good mobile base when he built one for the Blue Flamingo. His signature also has a link to good graphics for the work that lies ahead
since it was in a mold when the original stringers and deck were fitted, it might not seem to be outta shape, but you'd like it to be as close as possible to correct so you don't glass a deformation into hull while doing the stringers and etc
