.....A33 Track Pac group that included the four speed, Dana, 055 et al.
While the A33 does include the 3.54 Dana, it's not necessarily considered an 'axle package' like the others are.Odd...but true.
Every book & sales code manual that I've ever read says that "A33" is in fact an axle package which included the 054 radiator. My guess is that if you did not want an axle package, but did want a 4-speed, you got the DANA 3:54 and an 055 radiator? I wonder about the leaf springs and fan clutch in this case? Someone was kind enough to post build sheets earlier...gonna have a looksee...
