    The '86 has a footwell for the rear seat passengers. The '77 didn't have that feature. The shape of the frame was changed to accomodate the rear footwell in the newer K5's. You're in for a bit of fabricating to mate the two. /forums/images/graemlins/frown.gif

    I am not totally sure about where you live (fill out your profile) but older will be less restrictive as far as emisions go. If you want the look of the 86 you can always change out the front clip.

    Although if the body is shot, then it is a mute point.

    I've never tried to mate them, 'cause I'd heard that they aren't an easy fit. /forums/images/graemlins/frown.gif You'd need to start taking measurements on both frames and see just how much of a difference there is.

    my 77 body is rotted out, i live on the east coast, new brunswick, on the border with maine(canadian side). my frame is all sandblasted, sealed-epoxy primer, painted, as with everything else on the truck, total tear down, i can get an 86 or 87 body for 200.00 (about 100 US.. haha) this is why I ask about using the newer body on old frame, any more help greatly appreciated guys.

    Mine is an 85 body on a 76 frame if memory serves. You will have to have a minimum of 2 inch body lift and you will have to remove one crossmember from the older frame. The crossmember is behind the tcase and sits higher than the frame rails. Maybe a 3 inch body lift would clear it but never tried. Don't forget to put your own custom crossmember back in... All the body bolts line right up.
