'70 Dart 392 Project; what direction?

Rolled the engine back under this evening and got it bolted up. Had to narrow my engine dolly about 6” to get it to fit between cherry picker legs but once that was done it was very nice to install from underneath!
Going to get front suspension back on the car hopefully tomorrow and order some driveshaft components to weld up my own.
Anyone have any opinion on aluminum vs steel? My 5” aluminum on the diesel holds up amazingly well to 15-20k lb towing loads and 1k+’ft lbs, I’m leaning that way. Thoughts or opinions? TIA!

Shifter even lines up :) definitely going to either modify or make my own when the time comes. I imagine I’ll want it a little lower.
