Not sure what the torsion bars are. Is that the support structure under the skin? Does it matter if they are different? Will they fit? Given this is a RestMod project, I'm not concerned about the exact year accuracy, but certainly want things to fit properly. So if it is simply a matter that someone who's an expert on the YoY nuances might see the trunk open and noticed a '67 or '69 support structure on my '68 it wouldn't bother me. Bt if it's a fit/operational issue, I do care and hope you can clarify a bit ... many thx!
