Welcome here Doug. Great pictures you found. Thanx for sharing. Do you have more?
About the rear openings. There are probably not 2 LO23 Darts out there, even new, that have the same opening shape. They were modified by hand, torch, & hammer at Hurst. I'd even go to the extent the DS was different to the PS.
Below is a pic of mine. They've really been opened on the forward side, but still retain the original outer tubs. Available tire diameter started dictating opening size. There weren't tires available of size till the early 70's.
Anyone recognize the ID on that white Dart?
