'70 Dart 392 Project; what direction?

Making more progress but slowly. Initial testing my headlights would come on as would my dash lights but the headlight switch started turning in an odd manner and now no dash lights and no radio. Will dig into it some more once my new headlight switch shows up tomorrow.
Only turning on marker lights at the moment. Had to modify the rear marker housings to fit a newer style bulb socket. Battery is in the trunk and welded a ground stud to the frame on passengers side. Also got all my lights grounded. Also got the SRV delete plate on and a LS style throttle body with adapter plate. Don’t worry new wiper motor is en route this week as well.

I also noticed that with weight on the hotchkis springs my rear shackle is bottomed out on the frame. At this point I believe my option is a longer shackle or go to spring sliders…
