you would be surprised with the convertible if the torque boxes are good then chances are the inner rockers are good to and it's a sturdy setup. I had mine upside down on a rotisserie without a floorpan from the firewall to the rear tail panel and it never sagged.

and yeah the gaps were better than my 69 swinger with the 3exception of the right outer taillight on every darn 66 (and 65's) the right outer tail light doesn't line up really well with the trunk lid both 66's I have and all three of the 65's I had were that way. I fixed mine this time since it kept bugging me. this one is no tmine but you can see the shift, and if you raise the trunk lid to make it level the trunk is above the quarter panel that much.

(yeah not gonna happen in florida) it'll be white top. white interior and brilliant blue metallic paint WITH A/C. that's next on the list.
