    LE9 305 w ESC Performance upgrades '86 k5 Blazer

    Front bumper not mounted right

    My front bumper was dangling by three bolts when I bought the truck and when I tried to fix it the holes did not line upfrom left to right.My title says 1983 GMC. That little bracket on the driver side looks 73-80. I need you fine people to tell my what year my frame and bumper look like.
