My neighbor has a good deal on a 2 wheel drive 87 blazer in killer shape. It just a rolling chassis but all I want is the body to put on my 79 K10 shortbox. Does anyone know if the body mounts are the same, and if this body swap would work? Thanks.

first off, no the wheelbases are different, if you shorted the frame then yes it should work just fine and will take some modifying body mounts.  However, to the best of my knowledge the 2wd blazers werent made AFTER 82... so I doubt its an 87. If you could get some pics I could verify this for you. Feel free to email them to me, (prerunner1982@aol.com)..  for more info you might also check out www.67-72chevytrucks.com  They have a VERY active 73-87 board as well as a 4x4 and engine and drivetrain board.
