    I belive that everything from the cab forward should swap over. I'm not sure about the lift though, but pretty much everything else should bolt in.....

    Front springs will swap, but if the lift has rear springs, I think the 3/4 ton rear springs are 56" and the blazer has 52" rear springs. Im not positive about that though.

    Doors won't fit unless you cut down the ones off of your 78. Fenders, hood and all the other front end parts will interchange. All the suspension will bolt up unless your rear springs on the 78 are 56" long.

    Yeah, it's been a while dude! Looking to re-use those fancy fenders huh? /forums/images/icons/grin.gif

    The doors are pretty easy to do...if you need a template to cut yours I have a 74 door you could take measurements off of. I got it with my 74 for that exact reason. It's in bad shape but it's an original 74 door so you can see where the cuts need to be.

    If you don't want to do any cutting, find a door from '73 - '75. /forums/images/icons/wink.gif

    Wes, usually 73, 74 and 75 doors up here are pretty hard to find in decent shape. I haven't run across any here at all...much easier to cut newer doors.

    Aaron, the 74 doors are cut roughly at the top of the butterfly window and across horizontally at the window edge. Basically the part that frames the window gets removed. There are some caps and junk for seals that are needed but you can get those from LMC
