AC Car.. Drop In or Piece it Together AC System

My 69 Dart is factory AC car that I converted to 134 and then Hemi Swapped. Currently, the car is getting a re-fresh and the factory AC box is no longer an option. Was never really thrilled with it anyway. I'm switching to electronic pedal and an 8 Speed.. Neither is oem friendly when combined with the increased tunnel size and pedal to box interference.

I've read alot threads about the drop in unit, from classic air, for non ac cars. I know others have made adapters etc and it is possible, but is that the best direction? I'm struggling with which unit will fit best and produce the best cold air. I've seen others mention vintage air but not really go into any detail about what unit they went with or how they ran their lines. although I'm sure there is some info here about it and I'm just not seeing it.. . Not overly concerned about hidden lines and all that and I don't want a under dash unit.

Thanks for any input.
