Both in the pics will fit all bodies, the right one is an E-body only and the shorter one was on A,B,F bodies and trucks. As far as trucks I have found all the ones I have installed Tuff wheels on had no master splines. I have a tuff wheel on my 83 4x4 with the short adapter. I also have a tuff wheel on my 69 Dart with the short adapter but the adapter has a circumference larger than the column so there is a mismatch if you look closely at it.
