    In my 79 K5 the front cross member is snaped, is there any way I could replace it. And how would I go about doing it?

    Mine is cracked, the one under the motor mounts. You can grind down the rivets and punch them through. Then find a good one from the boneyard and bolt it in with some grade 8 bolts. I'm hoping ORD makes a HD one to go along with their crossover steering kit.
    Is anybody else's cracked?
    Is this commen?

    mine is cracked too. i want to replace it. but i am worried if i remove it the frame might shift and i will have a hell of time lining it back up. i was told to weld a diamond shape to it. i have thought of making my own crossmember out of tubing rather than a regular one, it will hold up much better and be much stronger. anyone else have any input?

    Depdog did a review of his cross-over steering conversion and part of it required a new cross member. If I remember he had some shop drawings of the tube cross member he fabricated. It looked quite heavy duty. Only one problem, I can't remember where I saw the article [​IMG] It either on this site somewhere or on Off-Road.com

    Mine never cracked, but the bolts came loose all the time. I just did crossover and built a new one simular to Depdogs, but out of 2 X 2 X 1/4 tube instead of 1 X 2 like Dep. I also bent mine on a tubing bender rather than segementing it like Deps. I like the way it turned out. If I had a digital camera I woudl post a pick of it. I dont think that you can just get one out of the junk yard though. I had to cut my old one in half to get it out from between the frame rails. As far as line up it is not a problem. Just take a floor jack with a 2 X 4 and gently jack up the motor at the harmonic balancer to realign the holes. You can see the one Depdog made on the main page under project vehicles I believe.

    I thought I was wrong once,
    but I was mistaken
