Just to give some serious clarification on Interchange for those that might not know.
The Blazer on the left is a 1991 chevy k5 fullsize blazer the one on the right is a 1992 chevy k5 blazer.Though the bodstyles outside fenders and doors and body style changed and transfercases and transmissions did change between the 2 the motors didn't.
The 1981-91 Chevy K5 blazer is interchangeable through these years though the older 73-80 Chevy k5 blazer doors will fit the 1981-91 chevy k5 blazers Thats the only part really.What im trying to say is 73-80 Chevy k5 blazers are upgraded using the newer parts not the reverse usually.
So in essence if the parts look anything like the 91 (LEFT PIC)then you are good.

The parts from that year span 1981-91 Chevy GMC k5 blazers(GMC Jimmy Fullsize blazer)will work with the 1984-87 M1009 Cucv military blazer.
BTW for those the 92 blazer was also used as a military cucv 2. :]
Some did ya know.The reasons the suburban and k5 blazers ran all the way into 91 was because Gm still had a bunch of parts from the Cucv and civy truck and k5 blazer run.The reason i know this is i have a civiy blazer we parted out that was all orgiinal with carced front fenders.Go figure a civy blazer now thats odd.:]
