Changing the rear quarters on my Dart conv. from a 69 to a 70

Not putting in a console. Car came with boxed rear springs ( convertible). Have had the bucket seat strengthening plates sitting in the garage since I bought the seats. I will be using a hydraulic TO bearing because I want to bypass any linkage issues and it seems that they work pretty smoothly compared to mechanical linkage. Another member also informed me that I will have to replace the trunk extension panels because they are different for 70-up, which I do have from the 70 I parted and they are beautiful shape. I like the 69 Dart GT emblems that originally came on the quarters just behind the doors so they are going back on. I have 3 floor humps that I had cut out of cars in the last 30+ years including one where I actually took some of the surrounding floor pan so that I would have a template if I ever wanted to cut the floor exactly like the factory did. I actually will convert my granny 6 cylinder column shift, bench seat 2 door into a factory MPFI 5.9 magnum ( will be running the stock injection system ) with a 4 speed and bucket seats before I get into the convertible project.
Sounds like you have a plan, but if it was me, I would add the SWINGER/flower emblem under the rear-side windows (one each side). If you cut and replace the rear section just before the rear side marker, it will hid any imperfections of the repair, under the swinger stripe. I could be wrong, but I think the GT emblem was installed on the front fenders, next to the front doors.
