Looks nice!
I bought some front seats from a 2013 Chrysler 200 convertible. Somewhat similar to your seats but integrated 3 point belts. Also have flip forward feature and power up/down/front/back.
I'm going to-
-strip out anything unneeded. (airbag and wiring, original brackets on sliders)
-make new mounting brackets
-anchor the rearmost part of the sliders through the subframe connector as I don't trust only the floor to hold the seat in place with the built in seat belts.
-remove chrysler 200 head rests and install 69 charger head rests
-reupholster in dark blue 69 Charger color/pattern and dye plastic parts blue.
-replace seat belts with blue belts
