I got the mamuals
the shop manual was for gmc must have hit the wrong key. There going to send me the one for chev Monday. I got the supplement manual.
It has a chart for load capacity. In the 4100-4400 section for gross vehicle weight.
10000 to 12000..then it has *14000 which is what I have . It says it does use 8 22.5 on the rear also it has H.D. 10-leaf main and 5 leaf auxiliary rear springs.
Is the H.D. or Hydrovac the type of rear end
Ive posted some pics.
