Andre, the box design changed in 55 - the mount points may differ and as you suspect, the 3/4's were all longbox, so yer dealin w/ long vs short - could always make a flatbed out of the AD tho grin

the AD cab wouldn't easily fit on the TF frame either - easier to head over to Sask and find a good TF cab!
