This is really stretching my poor memory cells because I did the installation in 1985, but I remember some of the things I had to do to make my 55 into a 4x4.
My 55 Cameo is a 4x4 conversion and I used the running gear from a 76 Blazer with the 203 transfer case converted to a part time unit. There is a slight difference in the width of the spring pads on the axles, but it was no problem to remove a little metal from the pads of the 76 axles and re drill for the different location of the spring bolt.
I used a different drag link and pitman arm, but I can't remember what vehicle donated the unit, except to say that it was a GM truck. I used the 55 spring pads and the 55 shock mounts. I am using the stock 55 steering box in the stock location.
Both the front and rear ends mount below the spring, and I needed to find longer U bolts and use lowering blocks between the rear springs and the new rear end to raise it up to match the height of the front.
My rear drive shaft had already been modified to mount an overdrive unit and I was able to use the Blazer drive shaft for the rear. I can't remember making any changes to the front shaft.
The Blazer front and rear end are wider than the original, but because the truck is raised by the installation, clearance is not a problem.
It was a lot of work, but all the problems can be solved by anyone with reasonable mechanical ability and the patience and desire to have a slick looking 4x4.
I am using the Blazer Ralley wheels. They stick out a bit, but there are no rubbing problems because the vehicle is raised 4 inches.
