Vintage Air Gen-IV Magnum in a dart

If you can find a local vintage air dealer He can loan you a Mock up Kit that has all the gen air units so you can decide which one is best for your application...just food for thought!!!....I had plenty of room in my 66 for the gen compac, probably enough for the unit you are looking at... its kinda like just fabricating some things to do what you need to do... I moved my wiper motor over a bit for some more room, however on your dart i don't think thats an issue...pulling the complete dash out makes for a much easier install..IMO
