    I could swear I made this post a few days ago, but for some reason it disappeared.

    I have a '79 frame and '84 cab and I've got to go buy bushings for it tomorrow. Do I get the ones for the older frame or the newer cab?

    I bought the new ones. I am thinking they're not going to work though, now that I look at it.

    I don't have my new frame here or I'd try it out.

    Anyone?

    I have done this type of conversion a few times in the past before.

    You will need the older year bushings to fit that '79 frame.

    The body's are pretty much the same on all the years. It's the frames that make the mount bushings different from '80 and older compared to '81 and newer.

    Trust me on this, get the '80 and older body mounts and you are done. /forums/images/icons/wink.gif

    what is the difference?
    the index hole or ???
    I think I have different mounts on mine
    old style for the front clip, new on the cab
    the body lift pucks are the same ones that were on the old frame and body.

    The older mounts are different heights.

    The '81 and newer mounts are all the same size bushings.

    The '80 and older frame body mounts (steel bracket part on the frame) are all different than the '81 and newer.

    If you put '81 and newer poly mounts on an '80 and older frame, the body lines will not line up properly and will sit lower in the back part of the cab. /forums/images/icons/wink.gif

    Ok, that means I've got to go back to the store and get the '70s bushings. No big deal.

    Are there any metal sleeves or shells or anything with the '70s bushings? From looking at the (I actually went to a friend's house to look under his truck) there aren't, but I just want to be sure.

    Hoping to have my truck done by the end of July. /forums/images/icons/smile.gif

    On the '73-'80 bushings, you will need to reuse the steel washer/pipe-thingies that you separate from the rubber mounts.

    You pull the steel parts from the rubber mounts and reinstall everything.

    Be aware for the pickup cabs, on the rear part of the cab mounts, the instructions with the poly mounts will tell you to take the long washer/pipe-thingie and cut it to the desired length in order to fit the lower poly bushing under the steel cab mount on the frame.

    Confusing? Probably. Just get the bushing kit and read the instructions. /forums/images/icons/wink.gif

    I know what you're talking about. I have the bushings now and the instructions. What I don't have is those steel pipe thingies. We're going to do without. /forums/images/icons/grin.gif

    You can always make some. Just get some big fender washers and some pipe. Cut the pipe to the correct length and weld them to the fender washers. Voila! You have the steel-thingies!

    Oh, BTW, GM does not sell these steel/pipe-thingies separate. You can still get them new, but you have to get them with the rubber bushings, too. /forums/images/icons/tongue.gif

    LMC truck sells them cheaper than GM does, but you still have to buy the rubber mounts to get the steel/pipe-thingies. /forums/images/icons/tongue.gif

    No welder or anything to cut metal here, so we're going to do without.
