68 charger hellcat swap

Swapping a hellcat from 2021 challenger donor car into a 1968 charger. Not sure what will need to be done as far as tuning goes to eliminate the security just to start the car. Customer wants to try to retain the factory display, gauges, and wants to use factory electric seats from the donor? He also asked about eliminating the multiple keys and have it set to one tune. Can anyone help with this? Is this possible

yes it is possible make sure to use a 2018 PCM harness and modals for ease of use and tune

i would use 2017 to 2015 if i did it
