    It is going great. I have the front suspension out and all I need to do is replace the front crossmember with a 4x one. I need to install the ORD crossmember, which will fit my 2x frame.

    I was thinking I would do the ORD crossmember then get a d44 and have cross over steering. what motor do you have and are the motor mount the same between 2wd and 4x4?

    got any pics?

    I have a 454 and the motor mounts are totally different. You can re-position them or get the competition mounts from ORD.

    I have the ORD crossmember and it looks like it is going to work. I have mocked it up, but I have to do some more stuff to the frame before I know for sure. Stephen with ORD is also waiting to hear if it works or not. It does not always fit 4x4, so you never know.

    Well, you need to go get yourself a grinder and some good grinding disks that are kinda tapered, so you can grind off the rivets.

    I completely de-bracketed (if that is a word) a K5 in about an hour. And I mean every bracket. The difficult part is removing the existing rivets that are leftover IN the brackets once they are removed.

    I will be using the B52's one the front of mine, so I have yet to remove them, but I do have a set 4x4 brackets and if I do not use them I'll sell them to ya for cheap or maybe we can trade.

    Have you checked out my picture gallery over at texas4x4.org? I do not think it has been hard at all, but then again I will cut anything up, just to see if I can.

    If I were you I would go get a WHOLE K5 or Burb to do the transformation. I traded up a bunch and then traded a few vehicles to get a good Blazer, but I needed it for all three of my conversions: 2 to 4, topless, and Fuel Injection......

    Next question.

    I am fairly certain I will ot use the body mount/spring hangers seeing that I am going with Kert's B52 system. I think $10 for everything will suffice. I will get them together this week.

    not trying to start any crap here, but wouldnt it be easier to start with a 4x4 and just swap over your engine and interior stuff? i know where there is a 3/4 ton 4x4 in good shape, but needs a motor. it's an 88' with an efi 350 that his son put a nice hole in the oil pan with the rod, but cheap. not sure what his bottom line would be, but probably around 800.

    if you have to preface your post with, "not trying to start crap"....then maybe you just shouldn't.......

    My 2WD happened to be my Grandfathers and I had alot of memories in as a child.......that's why.....

    like i'm supposed to know that. my point for not wanting to start crap is that if for some reason anyone wanted to do the work just because they wanted to, than who am i to say anything different. it was just a suggestion!! good luck with your build either way.

    That's exactly right, you wouldn't know that, and THAT is why you should not make gross generalizations.

    Now did you have a substantial question about the conversion or are yyou just going to hi-jack the thread somemore?

    Here is the Driver's B52 mounted for mock-up purposes only. I dusted it with white paint so I could mark the holes in the frame.

    Showing the front of the frame.

    Bracket removed and showing the holes that won't be drilled, but will be plug welded and the other holes that WILL be drilled for the bracket.


    [​IMG]

    Same story, different holes:

    Bottom of frame showing more of the same.

    Here is the ORD Xmember mocked in place.

    I also painted the areas where I had removed rivots and/or bolts for the sway bar brackets and front 2wd Xmember.

    If you can't take people offering information you don't need or in directions you don't want to go then maybe you shouldn't post either.:rolleyes:

    Chevyguy....I am finishing up my front mounts and then I am going to brace up the front frame by welding in some temporary braces before I take out the FRONT crossmember.

    My front does not have any holes in it, but yes I am going to change it out.

    The ORD crossmember is not even made for my application, per say, but Steven and I decided to move forward and FAB if I need to. See my truck is a factory BIG BLOCK, but they did not offer that option when I ordered mine.

    A factory engine crossmember should bolt in, but if not it is just a drilled hole away from fitting! :)

    I have some really good pics from one of the builds on here with the engine out and the crossmember installed. Once I get it installed I will post mine up for a reference for ya'll.

    Well I was in a welding mood, so I got the ORD frame repair somewhat welded in today.(welded the three rosebuds done)

    I also fabbed up some of the areas on the back where they were slightly rusted out and added some steel to join the two structures together.

    It is really coming along, well, as long as my welder keeps at this pace anyways.....
