Did 3/4 and 1 ton 4x4s both have the same front axles? how can i tell a dana 60 and a 14 bolt apart? also will any 73-87 chevy blazer burb truck 3/4 or 1 ton axle bolt right in? or is there diffrences in driveshafts and spring perches or width?

GM used the Dana 60 front from 1977 through the end of production of the V30 series crew cabs in 1991. My 2 door square body regular cab 1988 V30 has Dana 60 front.
When beefing up an old Blazer in the past the easiest/cheapest way was buy a square body K20 Suburban. They are cheap and usually have a Dana 44HD front and 14 bolt rear.
I bought this running 1979 with a good 400 sb, Turbo400 mated to a good working 203 transfer case with a planetary/shaft replacement style part time kit, tilt wheel, wagon style 8 lug 15"wheels, and many other good parts for $600 and parted it out. Parts of it are still going down the highway today in multiple vehicles.
