HELP! 1967-72 frame question

[70BigBlock]

I have a 70 SWB , frame is cracked so I need another frame to fit the 70 body. What year frame will fit my 70 body? 67-72??

technically all 67-72 frames though i would probably try and keep it a 2 wheel if it was a 2 wheel or a 4x4 if it was a 4x4, but i would avoid the 67 if you have power steering, that frame doesnt have the dent for the power steering unit

How bad is the crack? It may be repairable. I flexed mine a little too much on my Zr2 I had, cracked. I drilled what looked to be the end of the crack, and welded it. I put between 5000-7000 miles on it before I traded it to my buddy. Still hasn't failed on him yet.

Mine is a cOmplete crack top to bottom of frame. Is was welded back on but not the correct way.

I would clean up the crack chamfer the edges line it up properly tack weld it, add a support plate on each side and weld it all in, it will be easier than trying to switch frames and stronger than it was before it cracked.

To add to what blackdawn said. If your truck was coil spring make sure you try and find another coil spring frame, or you will have to move/swap some of the cross members around... and viceversa. I'm currently converting a leaf spring frame to coil spring. Its a little bit more work than I thought, but still not bad. Atleast the trailing arm brackets are already there. Still easier if you can find one as similar to yours as possible.
