1968 Barracuda 383 Big Block torque boxes ?????

These are my cars at present:

69 Dart GTS 383 4-speed front and rear boxes
67 Barracuda 383 4-speed rear boxes
69 Dart GTS 440 auto rear boxes
69 Dart GTS 440 auto rear boxes
69 Barracuda 440 auto rear boxes
68 Hemi Dart no boxes (been tubbed)
68 Dart GSS 440 auto rear boxes

BUT, I have had a couple of 67 GTS's with no boxes and a couple with rear boxes, one 68 Barracuda 383 auto with no boxes and a couple dozen big block A-Body's with ot without boxes. Lets not even get into the 340's...
