the convertibles have front and rear torque boxes
The chrome a pillar door frame is convertible only
trunk torsion springs are convertible only
Think windshield is same as hardtop - post car is different I think (been many years since I bought mine)
Mine was very solid. The floor and trunk is all original except the trunk 1/4 extensions
Barracuda and Dart convertible have some interchangable parts
Rear interior panels are being reproduced, seen the top latches in Mopar Collector Guide
Mine has a cloth top with glass back window
One thing I had to make was the spring steel wire supports at the end of the tack bow to push the sail panel out so not to rub a hole in the top. I believe this must have been a TSB after the cars were made and warranty issues were starting to cost Chrysler money. I had a retired Chrysler engineer research this and he could not find anything, but I have seen it on many convertibles.
My 67 Barracuda Convertible had rust everywhere, but as said before about the same as hardtop.
Mine does have some rust up in the right rear torque box that still needs repaired. Noticed as I was putting car back together.
If you have any questions send me a PM
I had all but 2 bolts out of my car. The axle bump stops on the rear frame rail are the only think that was left on the shell when we built it.
you can see the rear torque boxes in this picture
I have somewhere the build photo's, but don't think any from under showing torque boxes. If you know what Hemi B Body boxes look like these are about the same. I believe they are repo ing them also.
I have heard of the frame header rusting
do the tops leak, have not had a convertible/T Top car yet that does not leak some, but all the seals are available, fit like crap but available. I ended up using some of the original seals since they were in good shape and fit better than the new ones I bought
