How does one adjust the figment of the trunk lids? Put mine back on this week and it’s got some issues. The top corners and top edge fit good, but has issues along the side at spots.
It looks like either the lid got flattened, or the body got curved. Have you been doing some welding on either? Looks like the easiest way to fix that is to bend the lid to match. I'd pull it off and put a sawhorse under the midpoint, then have a friend help you push the front and back ends down. Go slow when bending, as it's harder to go backwards. Bend a little then try the fit. Bend more if needed. You can take a measurement from the front to the rear corners to see if they are getting closer together. A skosh is a lot in this case, so don't try for an inch the first time.
The proper way would be to remove the skin adjust the under structure to fit the opening and re attach the skin, since this should have been done well before mudding the fenders we’ll go from where your at, the quick and crude way, find a softwood 2x4 that bridges the fenders, put it between fenders and trunk lid where you need the curvature and very carefully push in the bottom , alternative is to also make some horizontal cuts in the under structure 3-5 maybe 3/4 inch apart where it need to bend, when you’ve got it where you want it tack the cuts, check it, adjust, then if it’s good weld it up
do you have the trunk seal in there,try that and see if it helps.If it doesnt help it shouldnt be too hard to "curve" the lid,set the bottom lip on the floor,and push the top edge down,it should bend easy,but be careful it could be too much .
