1968 Barracuda back space question

I like oldschool............. that's just how it was.
I miss those days.But if I could have them back, I'd like to keep the accumulated smarts from then to now, while having my 18 year-old body back,lol

Best thing I ever did was narrow my rearend and move the springs. Now all the popular wheels fit or can be made to fit with spacers, Shazzam!! And I can run at stock ride-height or slightly lowered, and the cops never stop me.
